Chapter 1

Factors affecting printer performance
Several factors affect the time it takes to print a job. Among these is
maximum printer speed, measured in pages per minute (ppm). Other
factors that affect printing speed include the use of special media
(such as transparencies, glossy media, heavy media, and customsize media), printer processing time, and download time.
The time required to download a print job from the computer to the
printer and then have the printer process the job depends on the
following variables:

Note

the complexity and size of graphics
color versus black and white
the printer’s I/O configuration (network versus parallel speed)
the speed of the computer you are using
the amount of printer memory installed
the network operating system and configuration (if applicable)
printer personality (PCL or PostScript 3 emulation)

Adding additional printer memory may resolve memory problems,
improve how the printer handles complex graphics, and improve
download times, but will not increase maximum printer speed (ppm
rating).

Controlling print jobs
There are several options available for controlling print jobs:

select printer settings through your software application or the
printer driver (recommended method)

select printer settings using the printer control panel
select printer settings using the new embedded Web server
enter printer commands directly into files
HP Web JetAdmin

Select printer settings through your software
application or the printer driver
The optimal way to control the printer is through your software
application or the printer driver. Changing these settings affects only
your print job. Most software applications allow you to choose printing
selections from menus within the software application. These
selections override the selections on the printer control panel.

Select printer settings using the printer control panel
You can also control the printer through the keys and menus of the
printer control panel. Changing these settings affects all print jobs. If
you are sharing the printer, coordinate control panel changes with
other users. For more information, see Chapter 2.
Note

Software application and printer driver settings override printer control
panel settings.

Chapter 1

Select printer settings remotely with the embedded
Web server
If you have a Web browser, you can use the printer embedded Web
server to control printer settings. To access the embedded Web
server, open your browser and enter the printer IP address or the
printer host name. You can print a configuration page from the control
panel to determine the printer address or hostname.
The embedded Web server allows complete remote control panel
functionality. Refer to Appendix E for details on how to use the
embedded Web server.
Note

To use the embedded Web server, you must have an IP-based network
and a Web browser. The embedded Web server can be used with
Microsoft® Internet Explorer 4 or above, and with Netscape Navigator 4
and above. IPX-based printer connections are not supported by the
embedded Web server.

Enter printer commands directly into files
Some software applications allow you to enter printer commands (for
example, escape sequences) directly into files. However, this method
of controlling your printer requires that you learn printer PCL
commands. For information on PCL printer commands, see
Appendix C or the PCL/PJL Technical Reference Package for this
printer. (See page 32 for ordering information.)

The HP Color LaserJet 4550 Series Printer

Managing memory
This printer supports up to 192 MB of memory. You can add additional
memory by installing Dual Inline Memory Modules (DIMMs). To allow
for memory expansion, the printer has three DIMM slots, which
accept 64 or 128 MB of RAM each. For information on installing
printer memory, see Appendix A.
The printer features Memory Enhancement Technology (MEt), which
automatically compresses page data to provide the most efficient use
of the printer’s RAM.
The printer uses 168-pin, nonparity, synchronous DRAM memory
modules. Extended data output (EDO) DIMMs are not supported.
Note

If memory problems occur when you are printing complex graphics, you
can make more memory available by removing downloaded fonts, style
sheets, and macros from printer memory. Reducing the complexity of
a print job from within an application can help in avoiding memory
problems.
This printer also includes HP Resource Manager, a new software
utility to assist with managing memory. For a full description of this
feature, see “HP Resource Manager” on page 27.

Chapter 1

Printer software
Included with the printer is a CD-ROM containing the printing system
software. The software components and printer drivers on this
CD-ROM help you use the printer to its fullest potential. See the
getting started guide for installation instructions.

Using the printer
control panel

Overview
This chapter helps you use the printer control panel to maximize
printer performance. This chapter includes the following sections:

Note

When to use the printer control panel
Locating printer control panel features
Control panel menus
Hard disk dependent menus
Printer information pages
Using the printer control panel in shared environments
Changing printer control panel configuration settings

Unless otherwise specified, “control panel” refers to the printer’s
control panel. Keys on the control panel are indicated by the KEY font.

Chapter 2

When to use the printer control panel
Hewlett-Packard has designed the printer control panel to facilitate
setting up default printer settings and to make printing selections
when your software does not provide them.
Use the printer control panel for overall configuration requirements, to
obtain printer status information, and to perform the following
procedures:

configure input trays for media type and size
take the printer online or offline
print configuration pages and menu maps
change printer default settings
verify available fonts

Software applications that provide print option commands allow you
to control print jobs through the software application rather than by
changing the printer control panel settings. The degree of control
varies among applications. Software commands override printer
control panel settings for all Printing Menu and most Configuration
Menu items.
Note

For information about controlling the printer in a network environment,
see the HP JetDirect Print Server Administrator’s Guide.

Using the printer control panel in
shared environments
The printer control panel functions essentially the same in shared
printer environments as it does when connected to a standalone
computer. If problems occur, contact your network administrator.
Because your printer is shared with other users, adhering to the
following guidelines will help ensure successful printer operation:

Note

Consult your system administrator before making changes to
control panel settings. Changing control panel settings could
affect other print jobs.

Coordinate with other users before changing the default printer
font or downloading soft fonts. Coordinating these operations
conserves memory and avoids unexpected printer output.

Be aware that switching printer personalities, such as Emulated
PostScript or PCL, affects the printed output of other users.

Your network operating system may automatically protect each user’s
print job from the effects of other print jobs. Consult your system
administrator for more information.

Chapter 3

Selecting print media
You can use many types of paper and other print media with this
printer. This section provides guidelines and specifications for
selecting and using different print media.
Before purchasing any media or specialized forms in quantity, verify
that your paper supplier obtains and understands the print media
requirements specified in the HP LaserJet Family Paper Specification
Guide.
WWW

See Appendix D for HP LaserJet Family Paper Specification Guide
ordering information.
For downloadable manuals, go to http://www.hp.com/support/lj4550.
When you connect, select Manuals.
It is possible that media could meet all of the guidelines in this chapter
and still not print satisfactorily. This may be due to abnormal
characteristics of the printing environment or to other variables over
which Hewlett-Packard has no control (for example, extremes in
temperature and humidity).
Hewlett-Packard recommends testing any media before buying it
in large quantities.

CAUTION

Using media that does not conform to the specifications listed here or
in the paper specification guide can cause problems that require
service. This service is not covered by the Hewlett-Packard warranty
or service agreements.

Do not use any media that produces hazardous emissions, or
that melts, offsets, or discolors when exposed to 190° C (374° F)
for 0.1 second.

Do not use paper that has already been printed on or that has
been fed through a photocopier.

Do not use paper with a watermark if you are printing solid
patterns.

Do not use transparencies that are not specified for use with
HP Color LaserJet printers.

Do not use paper that is embossed or coated unless it is
specifically recommended for use in this printer.

Do not use paper with irregularities such as tabs or staples.

Worldwide – http://www.hp.com/ghp/buyonline.html.

Transparencies
When printing on transparencies, use the following guidelines:

To prevent transparencies from bonding together, always send
them to the top output bin.

Handle transparencies using the edges. Oils from your fingers
that are deposited on the transparency can cause print quality
problems.

Use only overhead transparencies recommended for use in this
printer. Hewlett-Packard recommends using HP Color LaserJet
Transparencies with this printer. HP products are designed to
work together for optimum printing results.

Glossy paper
When printing on glossy paper, select the glossy print setting in the
printer driver. You can also use the printer control panel to set the
media type to GLOSS for the input tray you are using. Because this
affects all print jobs, it is important to return the printer back to its
original settings once your job has printed. See “Configuring input
trays” on page 76 for more information.
Note

Hewlett-Packard recommends using HP Color LaserJet Soft Gloss
paper with this printer. HP products are designed to work together for
optimum printing results. If you choose not to use HP Color LaserJet
Soft Gloss paper with this printer, print quality may be compromised.

Common printing tasks

Colored paper
Colored paper should be of the same high quality as white
xerographic paper. Pigments used must be able to withstand the
printer’s fusing temperature of 190° C (374° F) for 0.1 second without
deterioration. Do not use paper with a colored coating that was added
after the paper was produced.
The printer creates colors by printing patterns of dots, overlaying and
varying their spacing to produce various colors. Varying the shade or
color of your paper will affect the shades of your printed colors.

Envelopes
Note

Envelopes can only be printed from Tray 1. Hewlett-Packard
recommends configuring Tray 1 as a cassette and setting the tray’s
media size to the specific envelope size. See “Loading envelopes into
Tray 1” on page 80.
Adhering to the following guidelines will help ensure proper printing of
envelopes and help prevent printer jams:

Do not load more than 10 envelopes into Tray 1.

Envelopes should be flat.

Envelopes should be loaded with the flaps facing away from the
printer and toward the right side of the printer.

The weight rating of envelopes should not exceed
90 g/m2 (24 lb bond).
Do not use envelopes with windows or clasps.
Envelopes must not be wrinkled, nicked, or otherwise damaged.
Envelopes with peel-off adhesive strips must use adhesives that
can withstand the heat and pressures of the printer’s fusing
process.

Chapter 3

Labels
Note

For printing labels, Hewlett-Packard recommends configuring Tray 1 as
a cassette and setting the tray’s media type to LABELS in the printer
control panel. See “Configuring input trays” on page 76.
When printing labels, use the following guidelines:

Verify that the labels’ adhesive material can tolerate temperatures
of 190° C (374° F) for 0.1 second.

Verify that there is no exposed adhesive material between the
labels. Exposed areas can cause labels to peel off during
printing, which can cause printer jams. Exposed adhesive can
also cause damage to printer components.

Do not re-feed a sheet of labels.
Verify that labels lie flat.
Do not use labels that are wrinkled, bubbled, or otherwise
damaged.

Heavy paper
Use Tray 1 for paper that is heavier than 105 g/m2 (28 lb bond up to
42 lb bond). For optimum results when printing on heavy paper, use
the printer control panel to configure Tray 1 as a cassette and then set
the media type for the tray to HEAVY. Because this affects all print
jobs, it is important to return the printer back to its original settings
once your job has printed. See “Configuring input trays” on page 76.
CAUTION

Do not use paper that is heavier than the media specification
recommended for this printer. Doing so can cause misfeeds, paper
jams, reduced print quality, and excessive mechanical wear.

Common printing tasks

Preprinted forms and letterhead
Observe the following guidelines for best results with preprinted forms
and letterhead:

Forms and letterhead must be printed with heat-resistant inks
that will not melt, vaporize, or release hazardous emissions when
subjected to the printer’s fusing temperature of approximately
190° C (374° F) for 0.1 second.

Inks must be non-flammable and should not adversely affect any
printer rollers.

Forms and letterhead should be sealed in a moisture-proof
wrapping to prevent changes during storage.

Before you load preprinted paper such as forms and letterhead,
verify that the ink on the paper is dry. During the fusing process,
wet ink can come off of preprinted paper.

Recycled paper
This printer supports the use of recycled paper. Recycled paper must
meet the same specifications as standard paper. See the
HP LaserJet Family Paper Specification Guide. Hewlett-Packard
recommends that recycled paper contain no more than 5 percent
ground wood.
WWW

See Appendix D or http://www.hp.com/support/lj4550 for HP LaserJet

Chapter 3

Controlling print jobs
Among the aspects of a print job that you can control are the tray from
which the printer pulls media, the bin to which you send the job, and
the configuration for type and size of media for each tray. You can
control print jobs through the printer driver, your software application,
or the printer control panel.
CAUTION

To avoid affecting print jobs of other users, whenever possible, make
printer setup changes through your software application or the printer
driver. Printer setup changes made through the control panel become
default settings for subsequent jobs. Changes made through an
application or printer driver affect only that specific job.

Selecting output bins
This printer has two media output bins. The position of the door to the
rear output bin determines the bin used: If the door to the rear output
bin is open, media is directed to that bin. If it is closed, media is
directed to the top output bin. There are no driver or software options
for selecting an output bin. Figure 3-1 illustrates the top and rear
output bins.

Note

The top output bin holds up to 250 sheets of standard paper in
correct order, facing down. When the bin is full, a sensor directs
the printer to stop printing. Printing resumes when you remove
paper from the bin.

The rear output bin holds up to 100 sheets of standard paper in
reverse order, facing up. Use this bin when printing on small
media sizes. Because there is no sensor at this output bin, you
should monitor the bin and empty it when it is full.

If the rear output bin is open, duplex printing is not possible. Close the
rear output bin when duplex printing.
When printing on transparencies, close the rear output bin. This causes
the transparencies to be sent to the top output bin and reduces the risk
of jamming.

Common printing tasks

Selecting media by type
If you want to select media for your job by type of media rather than
by the input tray (source), you must first configure a printer tray for the
media type you are using, and then specify that media type in the
printer driver.
Selecting media by type rather than source is similar to locking out
trays and helps protect special media from accidental use. For
example, if a tray is configured for letterhead, and you specify in your
driver to print on plain paper, the printer will not pull the letterhead
from that tray. Instead, it will pull from a tray that has plain paper
loaded and that has been configured for plain paper on the printer
control panel.

Chapter 3

Configuring input trays
This printer allows you to configure input trays by type and size. This
allows you to load different media types and sizes in the printer’s input
trays and then request media by type or size.

Note

When the printer is used as a standalone printer, it might be
beneficial to configure the printer as TRAY 1 MODE=FIRST. In this
mode, if media is loaded in Tray 1 and no other tray is specified,
media will be pulled from Tray 1 regardless of the type or size of
media loaded in the tray.

When the printer is used in a network environment, it might be
beneficial to configure Tray 1 as TRAY 1 MODE=CASSETTE. In this
mode, the tray acts as a cassette-style tray and can then be
configured for media type and size.

If using the duplex printing accessory when Tray 1 is in FIRST mode,
be sure that the media loaded meets the specifications for duplex
printing. (See “Supported media weights and sizes” on page 67.)

Chapter 3

Printing from Tray 3 (optional 500-sheet paper
feeder)
The printer supports an optional 500-sheet paper feeder (Tray 3).
Tray 3 attaches to the bottom of the printer and serves as the printer’s
base. When the optional duplex printing accessory is installed, the
duplex unit must be positioned between the printer and the 500-sheet
paper feeder. The printer’s internal sensors detect the presence or
absence of Tray 3, and the printer control panel options automatically
adjust to reflect the current configuration.

Figure 3-2

Tray 3 (optional 500-sheet paper feeder)

Common printing tasks

The following are features of the 500-sheet paper feeder (Tray 3):

Note

The tray has a capacity of 500 sheets of standard paper. (See
“Supported media weights and sizes” on page 67.)

It is adjustable for specific media sizes, with corresponding stop
positions.

The printer detects media size based on Tray 3’s physical
configuration and the position of the media-size knob located on
the side of the tray.

A user-configurable control panel menu settings identifies the
media type that the printer expects to be loaded in Tray 3.

An internal sensor automatically detects when Tray 3 is empty.
A paper level indicator is provided on the front face of the tray.

The paper path for the 500-sheet paper feeder passes through Tray 2.
If Tray 2 is partially pulled out or removed, media from the paper feeder
cannot feed into the printer. This causes the printer to go offline and
generates a message that Tray 2 must be installed.

Using the optional duplex printing accessory for
two-sided printing
The optional duplex printing accessory (figure 3-3), enables you to
print on both sides of a page. In two-sided printing, known as duplex
printing or duplexing, the back side of the page is printed first. Then
the page is sent through the duplex printing accessory, where it is
flipped over and sent back through the printer for printing on the front.
Note

Although the printer detects the presence of the duplex printing
accessory, you must still specify duplex options in your software
application or in the printer driver in order to print on both sides of the
page.

Common printing tasks

Special printing situations
Use these guidelines when printing on special types of media.

Printing a different first page
Use the following procedure to print the first page of a document on a
different media type than the rest of the document. One example is
printing the first page of a letter on letterhead paper and the rest of
the letter on plain paper.
1

From your application or printer driver, specify a tray for the first
page (letterhead) and another tray for the remaining pages.

Load the letterhead into the tray that you specified in step 1.

Load the paper for the remaining pages of the document into
another tray.

You can also print on a different first page by using the printer control
panel or printer driver to set the types of media that are loaded in the
trays and then selecting the first and remaining pages by media type.

Printing on custom-size media
The printer supports single-sided printing on custom-size media. Tray
1 supports media sizes from 76 by 127 mm (3 by 5 in) to 216 by
356 mm (8.5 by 14 in), including B5 ISO. The only custom size
supported by Trays 2 and 3 is B5 ISO.
When printing on custom-size media, if Tray 1 is configured in the
printer control panel as TRAY 1 MODE=CASSETTE, you must set the
media size for Tray 1 to CUSTOM in the printer control panel. If Tray 1 is
configured as TRAY 1 MODE=FIRST, the printer will print on whatever
media is loaded in the tray. When printing on custom size (B5 ISO)
media from Trays 2 or 3, adjust the paper guides on the tray to the
Custom (B5 ISO) marking.
Some software applications and printer drivers allow you to specify
custom paper-size dimensions. Be sure to set the correct paper size
in both the page setup and print dialog boxes.
If your software application requires you to calculate margins for
custom-size paper, see the online Help for that application.

Chapter 3

Stopping a print request
You can stop a print request either from the printer control panel or
from your software application. To stop a print request from a
computer on a network, see the online Help for the specific network
software.
Note

It may take some time for all printing to clear after a print job is canceled.

To stop the current print job from the printer control
panel
Press CANCEL JOB on the printer control panel to cancel the job that is
currently printing. Pressing CANCEL JOB does not affect subsequent
print jobs that are stored in the printer buffer.

To stop the current print job from your software
application
If several requests have been sent to the printer through your
software, they may be waiting in a print queue (in Windows Print
Manager, for example). See your software documentation for specific
instructions on canceling a print request from the computer.

Common printing tasks

Job retention features
To use the Job retention features listed below, you must install a hard
disk in the printer and properly configure the printer drivers. All Job
retention features are selected in the printer driver. Some Job
retention features require you to use the printer control panel menus
to release the print job.
CAUTION

Make sure to identify your jobs in the printer driver before printing. Using
default names may override previous jobs with the same default name
or cause the job to be deleted.

Note

Adding additional printer memory may resolve memory problems,
improve how the printer handles complex graphics, and improve
download times, but will not increase maximum printer speed (ppm
rating).

Quick copying a job
The quick copy feature prints the requested number of copies of a job
and stores a copy on the printer’s hard disk. Additional copies of the
job can be printed later. This feature can be turned off from the driver.

Common printing tasks

Printing with the optional HP Fast InfraRed
Receiver
The HP Fast InfraRed Receiver enables wireless printing from any
IrDA-compliant portable device (such as a laptop computer) to the
HP Color LaserJet 4550, 4550N, 4550DN, or 4550HDN printer.
The printing connection is maintained by positioning the sending
infrared (FIR) port within operating range. Note that the connection
can be blocked by objects such as a hand, paper, direct sunlight, or
any bright light shining into either FIR port.
Note

For more information, see the user guide that came with the HP Fast
InfraRed Receiver.

Setting up to print with Windows 9x/NT
Before launching the InfraRed Driver, complete the following steps:
1

From the Printers folder, select the HP Color LaserJet 4550,
4550N, 4550DN, or 4550HDN as your default printer.

Choose Properties/Details for the HP Color LaserJet 4550,
4550N, 4550DN, or 4550HDN printer, and make sure that Virtual
Infrared LPT Port is selected.

Select the file to print.

Printing a job
1

Align your laptop computer (or other portable device equipped
with an IrDA-compliant FIR window) within 2 to 3 feet (1 meter)
maximum of the HP Fast InfraRed Receiver. The FIR window
angle must be within +/- 15 degrees to ensure an effective
connection for printing.

Print the job. The status indicator on the HP Fast InfraRed
Receiver lights up, and, after a short delay, the printer status
panel displays PROCESSING JOB.

If the status indicator does not light up, realign the HP Fast InfraRed
Receiver with the FIR port on the sending device, resend the print job,
and maintain the alignment of all devices. If you have to move the
equipment (for example, to add paper), make sure that all devices
remain within the range of operation to maintain the connection.

Chapter 3

103

If the connection is interrupted before your print job is complete, the
HP Fast InfraRed Receiver status indicator turns off. You have up to
40 seconds to correct the interruption and continue the job. If the
connection is resumed within this time, the status indicator lights up
again.
Note

The connection is permanently broken if the sending port is moved out
of operating range or if anything passing between the ports blocks
transmission for more than 40 seconds. (This block could be a hand,
paper, or even direct sunlight.) Depending on the size of the job, printing
with the HP Fast InfraRed Receiver may be slower than printing with a
cable connected directly to the parallel port.

Interrupting and resuming printing
The job interrupt and resume feature lets a user temporarily stop a job
that may be currently printing in order to print another job using the
FIR port. When the new job is finished printing, the interrupted job
resumes printing.
A user can only interrupt jobs that are printing and collating multiple
copies by connecting to the infrared (FIR) port on the printer and
sending a job to the printer. The printer stops printing the current job
when it reaches the end of the copy it is printing. The printer then
prints the job sent over the FIR connection. When the printer is done
printing that job, it resumes printing the original job with multiple
copies where it left off.

Common printing tasks

Using color

Overview
The HP Color LaserJet 4550 series printer, through a
combination of great technology and excellent engineering, offers
great color right out of the box. It provides a powerful blend of
automatic color features to generate superb color results.
This chapter explains the following topics:

Matching colors
HP ColorSmart II
Four-color printing (CMYK)
Matching PANTONE®* colors

Chapter 4

105

Matching colors
The process of matching printer output color to your monitor is quite
complex because printers and computer monitors use different
methods of producing color. Monitors display colors by light pixels
using an RGB (red, green, blue) color process, but printers print
colors using a CMYK (cyan, magenta, yellow, and black) process.
Several factors can influence your ability to match printed colors to
those on your monitor. These factors include:

Print media
Printer colorants (inks or toners for example)
Printing process (inkjet, press or laser technology for example)
Overhead lighting
Personal differences in perception of color
Software applications
Printer drivers
PC operating system
Monitors
Video cards and drivers

For most users, the best method for matching colors on your screen
to your printer is to print sRGB colors. The HP Color LaserJet 4550
uses HP ColorSmart II, which uses sRGB and automatically
optimizes color output. Keep in mind the above factors when colors
on your screen do not perfectly match your printed colors.

106

Using color

HP ColorSmart II
HP ColorSmart II is a set of technologies that enables optimal color
output automatically for diverse types of documents.
HP ColorSmart II utilizes object tagging and Standard RGB (sRGB)
color technologies. Object tagging allows optimal color and halftone
settings to be used for different objects on a page (text, graphics and
photos). The printer analyzes the page (what objects it contains) and
intelligently uses halftone and color settings that provide the best print
quality for each object. Object tagging, combined with optimized
default settings, produces great color out of the box.
In the Windows environment, you will find the HP ColorSmart II
Automatic and Manual settings on the Color tab in the printer driver.

Color management options
Print in Grayscale
Selecting the Print in Grayscale option from your printer driver prints
your document in black and white. This option is useful for previewing
preliminary copies of slides and hardcopy output quickly for color
document that will be photocopied or faxed.

Automatic color adjustment
The Automatic color adjustment feature of HP ColorSmart II (the
default setting) optimizes the color and halftones used for each
element in a document. Automatic also provides additional color
options for application and operating systems that support color
management systems. For more information, see your printer driver
online Help.
Note

Automatic is the default setting and is recommended for printing all
color documents.

Chapter 4

107

Manual color adjustment
The Manual color adjustment feature of HP ColorSmart II allows you
to adjust the color and halftone modes for text, graphics and
photographs. To access the Manual color options from the Color tab,
select Manual, then Options.
Halftone options
Halftone options affect the resolution and clarity of your color output.
You can select halftone settings for text, graphics, and photos
independently. The two halftone options are Smooth and Detail.

The Smooth option provides better results for large, solid-filled
print areas. It also enhances photos by smoothing out fine color
gradations.

The Detail option is useful for text and graphics that require sharp
distinctions among lines or colors, or images that contain a
pattern or a high level of detail.

Color map
The color map settings in the printer driver tell the printer how to
interpret the data sent from a software application into the final colors
that the printer will output. The color map settings can be adjusted to
Screen match or Vivid.

Screen Match (sRGB — standard red-green-blue) prints colors
that are optimized to match RGB monitor colors. Use this setting
to more closely match the colors on your screen.
sRGB is a world-wide color standard originally developed by HP
and Microsoft as a common color language for monitors, input
devices (scanners, digital cameras), and output devices (printers,
plotters). It is the default color space used for HP products,
Microsoft Operating Systems, the World Wide Web, and most
office software sold today. sRGB is representative of the typical
Windows PC monitor today and the convergence standard for
High-Definition Television.

Note

108

Factors such as the type of monitor you use and the room’s lighting can
affect the appearance of colors on your screen. For more information,
see the “Matching colors” section earlier in this chapter.

Using color

The latest versions of Adobe PhotoShop, CorelDRAW™,
Microsoft Office, and many other applications use sRGB to
communicate color. Most importantly, as the default color space
in Microsoft Operating Systems, sRGB has gained broad
adoption as a means to exchange color information between
applications and devices using a common definition that assures
typical users will experience greatly improved color matching.
sRGB combined with HP ColorSmart II improves the user's ability
to match colors between the printer, the PC monitor and also
other input devices (scanner, digital camera) automatically,
without the need to become color experts.

Vivid enhances the saturation of the printed colors to produce a
vivid color appearance. For more information, see your printer
driver online Help.

Chapter 4

109

Four-color printing (CMYK)
Cyan, magenta, yellow and black (CMYK) are the inks used by a
printing press. It is often called four-color printing. CMYK data files
are typically used by and originate from graphic arts (printing and
publishing) environments. The HP Color LaserJet 4550 series printer
is optimized to print RGB colors for a good match to the screen, but
will also accept CMYK colors through the PostScript printer driver.
By default, the HP Color LaserJet 4550 series printer interprets
CMYK data according to the Standard Web Offset Press (SWOP)
standard. This standard defines how a particular set of CMYK inks
should behave. The printer performs a SWOP color map and internal
half-tones to emulate a SWOP CMYK press. Emulations for
Dainippon Press (DIC) and Euro-standard CMYK inks used in the
Far East and Europe are also available, and can be selected from the
printer driver.

110

Using color

Matching PANTONE®* colors
The PANTONE® * Matching System colors are specified as CMYK
colors as supported in many graphics software applications. This
color-matching system is useful for matching printer output to a
specific color (for example, a logo). See the documentation for your
software application for instructions on using PANTONE® * colors.
For more information on using PANTONE® * colors, see the Readme
file for the PANTONE® * color-matching system included on the
printing system CD-ROM.
Note

Color settings, halftone settings, and print media affect the appearance
of PANTONE® * colors. To optimize PANTONE® *-certified colors, use
the default PostScript 3 emulation driver settings and HP LaserJet
paper.

Automatic PANTONE®* calibration
Automatic PANTONE® * calibration generates high-quality
PANTONE® * colors from the PANTONE® * color name automatically,
providing the best possible color calibration in the HP Color LaserJet
4550 printers. An example of a PANTONE® * name is: PANTONE® *
286CVC. When printing PANTONE® colors, Automatic PANTONE® *
calibration is the default setting for HP Color LaserJet 4550 printers.
This feature automatically converts PANTONE® * colors to optimal
color values for the HP Color LaserJet 4550 using the PANTONE® *
color name in the data stream sent to the printer.
Most application programs that support the use of PANTONE® * colors
for graphic objects will include the PANTONE® *name in the
PostScript output, along with the color values assigned to the object.
The HP Color LaserJet 4550 printer will recognize the PANTONE® *
name and substitute the optimum color values for the printer based
on color tables developed to provide the best possible match for each
specific PANTONE® * color within the printer’s color gamut.
No special actions are necessary in the application program or the
driver to enable this feature. You have the option of turning off
Automatic PANTONE® * calibration if you want to use applicationgenerated color values rather than HP-generated color values.

Chapter 4

111

To turn off Automatic PANTONE®* calibration

In Windows, go to Properties, Advanced, and then Printer
Features.

On a Macintosh, go to the CMYK Inks page of the driver
interface.

Applications known to generate PostScript files with graphic objects
preserving the PANTONE® * name are listed below:

Note

Adobe Illustrator 7 and 8
Adobe PageMaker 6.5
CorelDRAW 7, 8, and 9
Deneba Canvas 5*
Macromedia Freehand 7 and 8
Micrografx Designer
QuarkXpress 3 and 4

*Subsequent versions of Deneba Canvas no longer generate
compatible PANTONE® * names
Microsoft Publisher 2000 adds support for PANTONE® * colors but does
not preserve the PANTONE® * name necessary for this feature to work.
The Automatic PANTONE® * calibration feature only applies to
vector graphics, not picture (raster) data such as scanned images and
TIFF files. Adobe PhotoShop® , for example, being a raster image
editor, is not on the above list of applications that support the
Automatic PANTONE® * calibration feature.

WWW

PANTONE® * palettes for some raster image editor applications, such
as Adobe PhotoShop, are available on the Web at
http://www.hp.com/support/lj4550.
Once connected, select Downloads and Drivers. ICC color profiles,
sRGB color swatches, and printer drivers are also available at this Web
address.

112

Using color

PANTONE® * Application Palettes are available for:

Adobe Illustrator 4–8
PageMaker 5, 6, and 6.5
PhotoShop 3–5.5
CorelDRAW 6–9
Micrographics Designer 6–7
Macromedia Freehand 4–8
QuarkXpress (as EPS files) 3.3–4.04
Deneba Canvas 3.5–6.1
Fractal Design Painter 2–5.5
EPSF Charts
TIFF Charts
PANTONE® * Color Drive
Text Format (ASCII)
Raw PostScript File
Adobe Acrobat

Vector graphics such as company logos created in one of the above
applications (using palettes or applications preserving the
PANTONE® * name) can be imported into Microsoft Word, PowerPoint
or other MS Office applications. To do this, the color application must
create an Encapsulated PostScript (EPS) file of the image for
insertion as a file into the Office document using the insert file
function.
Note

Cutting and pasting from the clipboard will not work. These tasks do
not preserve the PANTONE® * name or the CMYK palette value.

Chapter 4

113

Some of the PANTONE® * colors will not match exactly. There are
over 945 PANTONE® * colors in the PANTONE® * Matching System.
These colors were created using sixteen inks on a lithographic
printing press. Not all of these colors are reproducible by a laser color
printer because they are out of a laser printer's 4-color range (gamut).
PANTONE® * calibrates HP printers to provide the closest match for
all the colors we can reproduce and provide the colors closest to
those we cannot reproduce.
Note

114

This feature requires the use of the PostScript 3 Emulation printer
driver. It utilizes a function in the PostScript language for describing
custom colors like PANTONE® * that is unique to PostScript and not
present in the PCL data stream. PANTONE® * colors are used mostly
in publishing environments by applications such as QuarkXpress and
Adobe InDesign that tend to use PostScript only.

Using fonts

Overview
This chapter provides information on various fonts. The chapter
includes the following sections:

Using internal TrueType fonts
Understanding printer default fonts
Selecting fonts
Printing a list of available printer fonts
Using fonts in PostScript Emulation
Using fonts on a network
Adding support for accessory fonts to a printer driver
Using special type effects
Hewlett-Packard custom font services

Chapter 5

115

Using internal TrueType fonts
TrueType is a font format developed jointly by Microsoft Corporation
and Apple Computer, Inc. Hewlett-Packard has included 80 TrueType
fonts with this printer, and matching screen fonts for use within
Windows.
You do not need to download these TrueType fonts because they are
already installed in your printer. The printer driver automatically uses
internal fonts when it can. This results in increased printing
performance.
See the Microsoft Windows documentation for specific instructions on
using TrueType fonts with Windows.

116

Using fonts

Understanding printer default fonts
The default font for this printer is 12-point Courier in the PC-8 symbol
set. The printer uses the default font only if another font has not been
specified.

Changing the default font
You can select a different default font from the printer control panel.
See “Selecting PCL fonts through the printer control panel” on
page 119.

Selecting a font other than the default

You can request a font from within most software applications.
You can send a PCL printer command requesting a font different
from the default. For information on printer PCL commands, see
Appendix B or the PCL/PJL Technical Reference Package for this
printer. (See page 32 for ordering information.)

Font selection priority
The printer selects printer fonts in the following order:
1

soft fonts (downloaded fonts)

fonts on DIMMs

internal fonts

In order to select a font, the font must be available from one of these
sources. If the font you request is not available, the printer selects the
closest match based on individual font characteristics (PCL only).

Chapter 5

117

Selecting fonts
You can select fonts either from a software application or through the
printer control panel.
Note

A font request from a software application or printer driver overrides
font settings in the printer control panel.

Selecting fonts from software applications
For information on changing font selection, base font, printer setup,
print options, and font appearance from a software application, see
the documentation for your application.

Selecting symbol sets
If you want to print a symbol such as Ω while the printer is in
PCL mode, you must first select the symbol set that contains that
character. See the PCL/PJL Technical Reference Package for a
complete listing of available symbol sets and printer commands. (See
page 32 for ordering information.)

Symbol set availability
Many software applications allow you to specify a symbol set from the
printer setup menu. You should consider two things when using
symbol sets:

Software applications may not support all of the printer’s symbol
sets.

Typefaces are designed to work with specific symbol sets.

Entering symbols into text
The documentation for your software application should contain
instructions for entering special symbols into text. See the
documentation’s index for phrases such as compose feature,
composite characters, symbol sets, character sets, code pages, and
extended characters.

118

Using fonts

Selecting PCL fonts through the
printer control panel
If your software application does not allow you to select fonts through
its menus, you can select PCL (TrueType) fonts through the printer
control panel. Only one font can be selected for a particular print job.
Note

A font selected through the printer control panel becomes the default
font for all subsequent print jobs.

You must specify several items when selecting a font through the
printer control panel. These items are listed on the printer’s font page
and include:

Note

the font source
the font number
the point size or pitch
a symbol set

A font request from a software application overrides font settings in the
printer control panel.

Chapter 5

119

To select PCL default fonts through the printer control
panel

Chapter 5

121

Interpreting the font lists
The PCL font list displays samples of available fonts. The following is
a description of the elements of the font list:
1

Font
The name of the typeface family.

Pitch/Pt
Pitch indicates the number of characters per inch of a fixed-space
font. Point Size is the height of the font, measured in points, and
is used to describe scalable fonts.

ESC Sequence
Escape Sequence (a PCL command) is used to select the
designated font. Fill in Pitch or Point Size and Symbol Set in the
boxes as required. The escape sequence contains a shaded box
followed by “v” or “h.” This indicates that you must enter the point
size (for example, 14.25v) or pitch (for example, 12.00h).

Font #
The number you use to select internal or downloaded soft fonts
from the control panel. The source of the font is also listed.
Note: Do not confuse the font number with the soft font ID.

Font ID
The identification number you assign to soft fonts when you
download them through your software.

See the PCL/PJL Technical Reference Package for instructions on
downloading fonts. (See page 32 for ordering information.)
The font list for PostScript Emulation displays all fonts installed in the
printer’s firmware. Although the characters are listed in only one size,
you can scale the typefaces to any size.

122

Using fonts

Using fonts in PostScript Emulation
The printer is configured with 80 scalable fonts that are available for
PCL and PostScript Emulation. The printing system installer on the
CD-ROM installs 80 fonts on your PC for use by any software
application.

Chapter 5

123

Using fonts on a network
Consult with your network administrator or with other network users
before using the printer control panel to change the default font and
before downloading or removing soft fonts and typefaces.
To conserve memory and avoid unexpected printer output, use the
guidelines that follow. Your network operating system might
automatically protect each user’s print job from the effects of other
print jobs in the network. Consult a network administrator for more
information.

Guidelines for printing with different fonts

124

The 80 internal fonts are available in PostScript Emulation (PS)
and PCL mode.

To conserve printer memory, download only those fonts that are
needed.

If you require several downloaded fonts, consider installing
additional printer memory.

Some software applications automatically download fonts at the
beginning of each print job. It might be possible to configure those
applications to download only soft fonts that are not already
resident in the printer. See your software application’s
documentation for more information.

Using fonts

Adding support for accessory fonts to a printer
driver
When you are using typefaces on DIMMs, your printer driver will
require information about the size, shape, and style of the type
characters so that it can format your text correctly.

Using special type effects
The printer can create special type effects, such as patterns, reverse
printing, mirrored text, and font rotation. See the user guide for your
application to verify that the application supports these features.
Developers can find complete instructions for using special type
effects in the PCL Technical Reference Package. (See page 32 for
ordering information.)

Chapter 5

125

Hewlett-Packard custom font services

Printer Interfaces

Overview
This chapter provides information on available printer interfaces.
The chapter includes the following sections:

Parallel configuration
Enhanced I/O (EIO) configuration
Configuring the printer for the network at the printer control
panel

Chapter 6

127

Parallel configuration
If your printer is not configured with a network interface card, connect
the printer to your computer using a bidirectional parallel cable
(IEEE-1284C compliant) with a “C” connector (see figure 6-1)
plugged into the printer’s parallel port. The cable can be a maximum
of 10 meters (30 feet) long. For ordering information, see “Printer
supplies and accessories” on page 31.
When used to describe a parallel interface, the term bidirectional
indicates that the printer is able to both receive data from the
computer and to send data to the computer through the parallel port.

Figure 6-1

Parallel cable “C” connector

Note

To use the enhanced capabilities of the bidirectional parallel interface,
such as bidirectional communication between the computer and
printer, faster transfer of data, and automatic configuration of printer
drivers, your printer driver must support these capabilities.
When you are using multiple ports, you can adjust automatic I/O
switching to maximize performance by using the timeout feature. If
data from other ports appears in the middle of your print job, increase
the I/O Timeout value. (See “Setting the I/O timeout” on page 61.)

128

Printer Interfaces

Enhanced I/O (EIO) configuration
This printer comes equipped with two enhanced input/output (EIO)
slots. These slots hold compatible external devices such as the
HP JetDirect print server network cards. Plugging EIO network cards
into the slots increases the number of network interfaces available to
the printer.
EIO network cards can maximize printer performance when you are
printing from a network. In addition, they provide the ability to place
the printer anywhere on a network. This eliminates the need to attach
the printer directly to a server or a workstation and enables you to
place the printer closer to your network users.
The printer control panel will have an additional menu (EIO Menu) if
the printer is configured with EIO network cards.

HP JetDirect print servers
HP JetDirect print servers (network cards) can be installed in one of
the printer’s EIO slots. These cards support multiple network
protocols and operating systems. HP JetDirect print servers facilitate
network management by allowing you to connect a printer directly to
your network at any location. HP JetDirect print servers also support
the Simple Network Management Protocol (SNMP), which provides
network managers with remote printer management and
troubleshooting through HP Web JetAdmin software.
Note

Installation of these cards and network configuration should be
performed by a network administrator.

You might need to configure certain network parameters on the
printer. You can configure these parameters from the printer control
panel, the embedded Web server, or for most networks, from the
HP Web JetAdmin software (or the HP LaserJet Utility for Macintosh).
The utilities are provided on the printing software CD-ROM that
comes with the printer.
Note

The embedded Web server is a new printer feature from HP. For more
information about using the embedded Web server, see Appendix E.
For a complete list of supported networks and for instructions on
configuring network parameters from software such as the HP Web
JetAdmin software, see the HP JetDirect Print Server Administrator’s
Guide. The guide comes with printers in which an HP JetDirect print
server is installed.
This section contains the following instructions for configuring
network parameters from the printer control panel:

configuring Novell NetWare frame type parameters
configuring TCP/IP parameters
configuring the Apple EtherNet phase parameters
disabling unused network protocols

Configuring Novell NetWare frame type
parameters
The HP JetDirect print server automatically selects a NetWare frame
type. Select a frame type manually only when the print server selects
an incorrect frame type. To identify the frame type chosen by the
HP JetDirect print server, print a configuration page from the printer
control panel.

Cleaning the printer
Cleaning excess toner from the printer
Toner from the yellow, magenta, and cyan toner cartridges will
accumulate on the flaps that cover the toner cartridges. Although this
accumulation of toner does not cause any print defect, the excess
toner needs to be cleaned from the flap occasionally. Clean the flap
covering the toner cartridge and other excess toner from the printer
when you are replacing toner cartridges. There is a toner cloth
provided with each replacement toner cartridge to clean the toner
from the printer. See the instructions included with the replacement
toner cartridge for more information about cleaning the printer.
CAUTION

Do not use the toner cleaning cloth on the drum, developer sleeves in
the toner cartridge, or transfer rollers. Doing so can damage these units
and cause other print quality problems.
If toner has built up on the toner cartridge, it may fall onto the transfer
roller, which causes streaking on the media being printed. To clean
the toner from the transfer roller, print several blank pages until the
streaking stops.

Printer control panel
messages

Overview
This chapter lists printer control panel messages and explains
their meaning. The control panel displays four types of
messages. These message types are:

Status messages
Warning messages
Attention messages
Critical error messages

Chapter 8

151

Message types
Status messages
Status messages reflect the current state of the printer. They inform
the user of normal printer operation and do not require user
interaction to clear them. They change as the state of the printer
changes. Whenever the printer is ready, not busy, and has no pending
warning messages, the status message READY is displayed if the
printer is online. If the printer is offline, the message OFFLINE is
displayed.

Warning messages
Warning messages inform you of data and print errors. These
messages typically alternate with the READY or OFFLINE
messages and remain displayed until you press GO. If CLEARABLE
WARNING is set to JOB in the printer’s configuration menu, then
these messages are cleared by the next print job.

Attention messages
Attention messages inform you that some action must be taken, such
as adding paper or clearing a paper jam. For certain errors, the
printer continues printing without user intervention. If AUTO
CONTINUE is set to ON in the configuration menu, the printer will
automatically attempt to return online.

Critical error messages
Critical error messages inform you of a device failure. You can clear
some of these messages by turning the printer off and then on. These
messages are not affected by the AUTO CONTINUE setting. If a
condition persists, service is required.

Basic troubleshooting checklist
If you are experiencing problems with the printer, this checklist may
help identify the cause of the problem.

Is the printer connected to power?

Were recently installed consumable items (fuser kit, transfer kit,
imaging drum kit) installed correctly?

Is the power switch (standby button) pushed in?

Is the printer in the READY state?
Are all necessary cables connected?
Are any messages displayed on the control panel?
Were recently replaced toner cartridges installed correctly? Was
the pull tab on the cartridge removed?

If you cannot find solutions to printer problems in this guide, contact
an HP service and support center. (See “Support information” on
page 250.)
For additional information on installation and setup of the printer, see

The media does not meet HP specifications. Use media that
meets HP specifications (see page 67).

The toner cartridge is defective, replace the toner cartridge.

The transfer roller is dirty or worn.

There is excess toner inside of the printer. Clean the printer (see
page 148).

Banding and horizontal lines
Banding occurs when solid fill areas show streaks or bands of shade
variations. This can be caused by:

Consumables that are beyond their life.
Improper consumable storage.

If the problem persists:

Print a configuration page to check the life of the consumables.
Replace any consumable that is past its rated life.

Banding is more visible in some halftone patterns than others. If
the defect occurs only once on a letter- or A4-size sheet, try
printing the pattern on a legal- or A3-size sheet.

Observe the following from the test sample:
• Check to see if the defect spans all color planes.
• If the defect is in all color planes, does the defect produce a
straight line through all color planes, or does it move from one
color plane to the next?
• If the defect moves from one color plane to the next, measure
the amount it moves. This movement amount is called the
“procession.” Keep in mind the print order is K-M-C-Y. Measure
the procession from K to M or M to C, not K to C.

CAUTION

Do not expose the imaging drum to light for more than 15 seconds. The
drum is light sensitive, and exposure to light can cause permanent
damage.

the document.

There is a problem with the network configuration. Some sharing
devices on networks may generate a blank page as a separator.
• Check with the network administrator.

The printer may be feeding two or more pages at once because
the paper is difficult to separate.

The sealing tape has been left in the toner cartridge. Remove the
sealing tape from the toner cartridge color that is missing from
the printed image.

the imaging drum.

Do not expose the imaging drum to light for more than 15 seconds. The
drum is light sensitive, and exposure to light can cause permanent
damage.

Chapter 9

205

Imaging drum defects
Causes:

Damage such as scratches or dents on the imaging drum. These
usually appear as black or white marks on the page.

Paper dust adhering to the imaging drum. These usually appear
as white marks in the dark printed areas of the page.

Exposure of portions of the imaging drum to light. This causes
light sections in the printed output. The life of the imaging drum is
shortened by exposure to light.

Actions:

206

Print at least four configuration pages to determine if the defect
repeats in the same horizontal orientation.

Inspect the imaging drum for scratches, dents, or other damage.
Replace if needed.

If the problem is dust, remove the dust with isopropyl alcohol
applied with a lint-free, static-free wipe. Try this only if the print
defect is unacceptable and the only other alternative is replacing
the imaging drum.

Defects caused by exposure to light might clear up over time. If
severe, replace the imaging drum.

Solving problems with the printer

Overhead transparency defects
Overhead transparencies may display any of the image quality
defects shown in the previous samples. In addition, because
transparencies are pliable while in the print path, they are subject to
being marked by the media-handling components.
Note

WWW

Allow transparencies to cool at least 30 seconds before handling them.

Make sure that “transparency” is checked as the media type in
the Paper Tab in the printer driver. Also, make sure that the media
input tray is correctly configured for transparencies. When
Transparency is selected as the media type and ColorSmart II is
selected on the Color tab, the printer will use a color treatment
optimized for projection.

If transparencies show lines and creases in the media and/or the
printed output, compare the defect against the repetitive defect
ruler (page 195) to help isolate the cause to a particular
component.

Check that the transparencies meet the specifications listed in the
HP LaserJet Family Paper Specification Guide.

If the transparencies have spots or smudges, reprint them being
careful not to touch the surface of the media. Skin oils can
contaminate transparencies, causing spots and smudges.

Small random dark areas on the trailing edge of solid fill pages
may be caused by transparencies sticking together in the face up
bin. Try printing the job in smaller batches.

Send transparencies only to the face-down output bin.

Transparencies created on the printer may look rough, but they can
still be used successfully on reflective-type (portable) transparency
projectors.

Chapter 9

207

Dull or dark transparencies

If the transparency colors are dull or dark, ensure the
transparencies meet the specifications for this printer (part
number C2934A for letter, and C2936A for A4).

The selected colors are undesirable when printed. Select different
colors in your software application or printer driver.

Spots and smudges appear in the background areas of
transparencies when they are projected. Oil from your hands can
cause spots or smudges on transparencies. Reprint the
transparencies, being careful not to touch the surface of the
transparencies.

You are using a reflective overhead projector. Use a standard
overhead projector.

Rippled or wavy transparencies

Solving problems with the printer

DIMM Installation

Overview
The printer is designed for easy installation of additional memory.
This chapter provides information on installing memory.

Appendix A

215

DIMM configuration
This printer supports up to 192 MB of memory. You can add additional
Random Access Memory (RAM) to this printer by installing Dual
Inline Memory Modules (DIMMs). The printer uses 168-pin,
non-parity, synchronous DRAM memory modules. Extended Data
Output (EDO) DIMMs are not supported.
You can install 64 or 128 MB DIMMs into either of the printer’s
available 168-pin DIMM slots.
CAUTION

Do not attempt to remove the DIMM in slot #1 (see figure A-1). The
DIMM in slot #1 is part of the printer’s firmware. Removing it will affect
printer operation.

Figure A-1

Do not remove the DIMM in slot #1.

216

DIMM Installation

Installing DIMMs
To install a DIMM

CAUTION
To reduce the possibility of damage
caused by static electricity, always wear
an electrostatic discharge (ESD) wrist
strap or touch the surface of the
antistatic package before handling
DIMMs. When handling the formatter
board, wear an antistatic wrist strap or
frequently touch bare metal on the
printer.
1

Turn the printer off and wait for the
fans to stop. This will take a few
minutes.

2
CAUTION
Wait for the printer’s fans to turn off
before unplugging the printer.

Disconnect all power and interface
cables.

Locate the formatter board in the
upper-left corner of the rear of the
printer and loosen the six screws.

Appendix A

217

Slide out the formatter board and set
it on a clean, flat, grounded surface.

Align the connectors on the DIMM
with the notches in the DIMM slot.
Insert the DIMM into the slot and
then firmly push the DIMM lift locking
levers into position.

Note
Repeat step 5 for each DIMM you are
installing.
6

Insert the formatter board into the
printer.

218

DIMM Installation

Tighten the screws.

Reconnect the power and interface
cables.

Turn the power on. The printer
automatically updates the memory
configuration to include the newly
installed DIMMs.

Appendix A

219

Verifying DIMM installation
To verify that the DIMM installation was successful, print out a
configuration page (see Chapter 2). If the DIMM has been installed
properly, the figure in the Memory section of the configuration page
will reflect the new total amount of memory. If the DIMM contains
resources such as fonts or macros, those will be displayed on the
printer’s test pages.
If the printer control panel displays an error message, see Chapter 8
for descriptions of printer control panel messages.

220

DIMM Installation

Resource saving/permanent resources
Utilities or jobs that you download to the printer sometimes include
resources (for example, fonts, macros, or patterns). Resources that
are internally marked as permanent remain in the printer’s memory
until you turn the printer’s power off.
Use the following guidelines if you make use of the PDL (page
description language) ability to mark resources as permanent. For
technical details, see an appropriate PDL reference for PCL or PS.

Note

Mark resources as permanent only when it is absolutely
necessary that they remain in memory while the printer's power is
turned on.

Send permanent resources to the printer only at the beginning of
a print job and not while the printer is printing.

Overusing permanent resources or downloading them while the printer
is printing might decrease the printer’s performance or its ability to print
complex pages.

Appendix A

221

Installing EIO cards/mass storage
Turn off the printer before installing the EIO card or mass storage
device.
See the following figure for orientation and location of the EIO card or
optional mass storage device, such as a hard disk.
Use HP Resource Manager to manage fonts on a mass storage
device (page 27). For more information, see the printer software help.
HP is constantly introducing new software tools for use with your
printer. These tools are available from the Internet free of charge. See
page 12 for how to visit the HP website for more information.
After you have installed a new device, print a configuration page (see
page 49).

222

DIMM Installation

PCL commands

Overview
This printer supports the use of the Printer Control Language
(PCL). Most software applications provide the printer with
necessary language information. However, some applications do
not provide the printer with language information and require the
user to enter printer commands. See your software application
documentation for instructions on entering printer commands.
This appendix is not intended to provide comprehensive
information about PCL commands. Rather, it provides a quick
reference for users who are already familiar with the PCL
command structure.
WWW

For more information, see the PCL/PJL Technical Reference
Package. See page 32 for ordering information or visit
http://www.hp.com/support/lj4550.

Appendix B

223

PCL commands
PCL printer commands instruct the printer which tasks to perform or
which fonts to use for specific print jobs.

PJL commands
The HP Printer Job Language (PJL) provides control above PCL and
other printer languages. The four major functions provided by PJL
are:

printer language switching
job separation
printer configuration
status feedback from the host

PJL commands can be used to change printer default settings.

224

PCL commands

Interpreting PCL printer command syntax
Before using printer commands, compare the following characters:

Note

Lowercase L:

Uppercase O:

Number one:

Number zero:

You must use the exact character and case specified for PCL printer
commands.
Many printer commands use the lowercase letter L (l) and the
number one (1), or the uppercase letter O (O) and the number zero
(0). These characters may not appear on your screen as shown here.
Figure B-1 shows the elements of a typical printer command (in this
example, a command for page orientation).

Figure B-1

Printer command elements
1

Escape character (begins the escape sequence)

Value field (contains both alpha and numeric characters)

Category of command

Uppercase letter (terminates the escape sequence)

Appendix B

225

Combining escape sequences in PCL Printer
command syntax
Escape sequences can be combined into one escape-sequence
string. There are three important rules to follow when combining
code:

The first two characters after the character must be the
same.

When combining sequences, change the uppercase (termination)
character in each individual escape sequence to lowercase.

The final character of the escape sequence must be in
uppercase.

The following escape sequence would be sent to the printer to select
legal paper, landscape orientation, and eight lines per inch:
&l3A&l1O&l8D
The following escape sequence sends the same printer commands
by combining them into a shorter sequence:
&l3a1o8D

226

PCL commands

Entering escape characters

PCL printer commands always begin with the escape character
().

Selecting PCL fonts
The printer font list provides PCL printer commands for selecting
fonts. (See “Printing a list of available printer fonts” on page 121.) A
sample section of a font list is shown below.
There is one variable box for entering symbol sets and one for
entering point size. Unless these variables are entered, the printer will
use defaults. For example, if you want a symbol set that contains linedraw characters, select the 10U (PC-8) or 12U (PC-850) symbol set.
Other common symbol set codes are listed in the “Common PCL
Printer Commands” section of this chapter.

PCL commands

Note

Fonts are either fixed or proportional in spacing. This printer supports
fixed fonts (Courier, Letter Gothic, and Lineprinter) and proportional
fonts, including CG Times, Arial®, and Times New Roman.
Fixed-space fonts are best used in applications such as spreadsheets
and databases, where it is important for columns to line up vertically.
Proportional-spaced fonts are generally used in word processing
applications.

Embedded Web
server

Introduction
This printer is equipped with an embedded Web server, which
allows you to access information about printer and network
activities. This chapter explains the features and functionality of
the embedded Web server.

Appendix E

259

Using the embedded Web server
The embedded Web server allows you to view printer and network
status and to manage printing functions from your PC instead of from
the printer control panel. This service is designed for offices using an
IP network and a standard Web browser. Below are examples of what
you can do using the embedded Web server:

view printer control panel messages
determine the remaining life on all consumables
order consumables
view and change tray configurations
view and change the printer control panel menu configuration
view and print internal pages
receive notification of printer events
view and change network configuration

To use the embedded Web server, you must have an IP-based
network and a Web browser. The embedded Web server can be used
with Microsoft Internet Explorer 4 or above, and with Netscape
Navigator 4 and above. IPX-based printer connections are not
supported by the embedded Web server.

To access the embedded Web server
1

Open your Web browser.

Type the IP address assigned to the printer into the Address or
Location field.

If you do not know the IP address for the printer, it is listed on the
printer configuration page. For more information about printing a
configuration page, see “Printer configuration page” on page 49.

260

Embedded Web server

Embedded Web server page sets
The embedded Web server has three sets of internal Web pages for
collecting information about the printer and for changing configuration
options. These sets are:

Home pages
Device pages
Networking pages

When the embedded Web server is active, each set of pages is listed
on the browser screen. Click on the set that you want to view, and the
selection expands to display a list of frequently accessed Web links.
Note

Each page in the embedded Web server has access to online Help.
For more information regarding a particular page, click the Help button.

Home page set
The home pages of the embedded Web server are the informational
pages for the printer. These include:

Printer Status page
This page displays printer capabilities, control panel messages,
and status lights that currently appear on the printer control
panel. From here, you can set the frequency at which the
embedded Web server will check the printer status. This page
also displays consumable life levels and the input tray
configurations.

Configuration page
This page displays the printer configuration page. For more
information about interpreting and printing the configuration page,
see page 49.

Supplies status page
This page displays the levels of the consumables for the printer.
For more information about interpreting and printing the supplies
status page, see page 53.

Usage page
This page displays the amount of each media type that has been
used by the printer. For more information about interpreting and
printing the usage page, see page 55.

Event Log page
This page displays the printer’s event log. For more information
about interpreting and printing the event log, see page 56.

Appendix E

261

Device Identification page
This page displays the name, asset number, network address,
model number, and serial number for this printer. To set the name
and asset number, see the description of the “Device
Identification page” under “Device page set”.

Device page set
The device pages of the embedded Web server allow you to
configure the printer from your PC. The device pages can be
password protected. Always consult with your network administrator
before changing the printer’s configuration.

Configure Printer page
Configure all printer settings from this page.

Alerts page
Input a list of recipients for electronic notification of various printer
events.

E-Mail page
Configure the incoming and outgoing mail servers.

Security page
Set a password for the embedded Web server. Passwords and
features configuration should only be determined by the network
administrator. If a password is set, users will require a password
for entry into the device sections of the embedded Web server.

Other Links page
Add or customize links to other websites. These links are
displayed on the navigational bar throughout the embedded Web
server pages.
There are two permanent links, “Ask a question” where the user
can get help with the printer, and “Order Supplies” where you can
order printer supplies. Order Supplies is only available from the
Device page set.

262

Language page
Determine the language in which to display the embedded Web
server information.

Device Identification page
Name the printer and assign an asset number to it. Input the
name and email address of the primary point of contact for
information about the printer. This page also shows the printer’s
network names, addresses, and printer model information.

Embedded Web server

Networking page set
This set of pages allows the network administrator to configure the
HP JetDirect card for the printer. Refer to the online Help and to the
HP JetDirect Print Server Administrator’s Guide for more information.
