Glossary
A4 Size
A standard paper size used in Japan and other countries. Paper is 210 X 295 mm
(8.25 X 11.6 inches).
Application Software
Software programs that perform tasks on a computer. Such programs include word
processing, database management, and accounting, for example.
ASCII
The acronym for American Standard Code for Information Interchange. ASCII is a set
of 256 codes (numbered 0 to 255) used to communicate information between a
computer and another device such as a printer.
Baud Rate
The speed, in bits per second, at which data is transmitted to a device such as a
printer. Baud rates apply to serial data only. 200 baud equals approximately 120
characters per second.
Bidirectional Printing
Alternate printing of lines from left to right and right to left. Bidirectional printing is
faster than unidirectional printing because there are no carriage returns.
Bit
The smallest unit of information in computer memory. A bit is a single digit, either a 1
or a 0, in the binary numbering system. Eight bits equal one byte.
Buffer
A storage area for data in the printer or computer. The printer’s buffer consists of a
print buffer and a download buffer. The print buffer holds the data to be printed. The
download buffer holds downloaded data such as download (soft) fonts.
Byte
A byte consists of eight bits that constitute one symbol. A byte represents a single
character, such as number, letter, or special control character.
Carriage Return (CR)
The return of the print head carriage to the beginning of the next line.
Centronics Interface
A type of parallel interface. See Parallel interface.
Column
A vertical section on a printed page. This printer can print 80-column pages at 10-pitch
(10 characters per inch).
Command Set
A set of print and format commands used to control the printer. Each printer has its
own resident command sets embedded in the printer firmware. These command sets
are actuated by codes sent from the host computer.
Glossary
Condensed Print
Print that uses “condensed” characters. Condensed characters are narrower than
regular characters. Using condensed print increases the number of characters per line.
Continuous Forms
Connected, fan-folded sheets of paper that are fed into the printer using forms tractors.
The fan-folded sheets are separated by tearing them at their perforations.
Control Panel
A panel containing the printer indicators and buttons. The control panel is used to
control printer operations, such as loading paper, selecting print features, and
changing Set-Up options.
cpi
Characters per horizontal inch. Also referred to as pitch. For example, 12-pitch means
12 cpi.
cps
Characters per second.
Cut Sheets
See Single sheets.
Defaults
Settings selected automatically by the printer when the power is turned on. Enter the
Set-Up mode to change the defaults to ensure compatibility with your system hardware
and software.
Dot Matrix
The grid used to print characters on a dot matrix printer. Each dot corresponds to a
wire in the print head.
Downloading
Transferring soft fonts from the computer to the printer’s memory. Downloading allows
you to use fonts not resident in the computer.
dpi
Dots per inch.
Emulation
A set of instructions that control how data is transmitted between devices such as a
computer and a printer. This printer has two resident emulations: IBM proprinter
XL24E, and Epson EP2.
Font
A complete set of printable characters having the same size and style. For example,
Courier 10 and Prestige Elite 12 are commonly used fonts.
Form Feed (FF)
A signal to the printer to advance the paper forward one page. Form feeds can be
executed either by your software or by pressing the FF/LOAD button on the printer
control panel.
GL-2
Glossary
Graphics Printing
Controlling the print head wires (dots) individually to produce a picture or an image on
the page.
Hexadecimal
A base-16 numbering system (also commonly referred to as hex numbers). Since a
base-16 system requires 16 digits, numbers 0 through 9 and letters A through F are
used. Expressing binary numbers in hexadecimal uses fewer digits.
Hex Dump
A hexadecimal printout of control codes and data. Hex dumps are used to debug
computer programs and to troubleshoot printer malfunctions. To print a hex dump on
the printer, use the HEX-DUMP option of the TESTS function in the Set-Up mode.
Interface
A connection that allows communication from one part of a system to another. For
example, electrical signals are transferred between the computer and printer over an
interface cable.
K Byte
Kilobyte. 1K byte equals 1024 bytes.
Letter Size
A standard paper size used in the United States and other countries. Paper is 8-1/2 X
11 inches (215.9 X 279.4 mm).
Line Feed (LF)
A signal to the printer that advances the paper forward one line
Line Spacing
The vertical spacing between lines, measured in lines per inch.
lpi
Lines per inch. Used to measure line spacing.
Monospacing
Character spacing in which each printed character has the same width. Also called
fixed pitch, monospacing is the opposite of proportional spacing. Typewriter or
computer-printed text is typically monospaced.
Nonresident Font
Fonts not present (resident) in the printer’s permanent memory. Soft fonts are
examples of nonresident fonts. (This printer does not support font cards.)
Normal Mode
One of the printer’s two operating modes. In Normal mode, the control panel can be
used to perform everyday printer operations, such as loading and unloading paper,
feeding paper, and selecting print features. See also Set-Up mode.
Offline
When the printer is offline, it receives commands from the printer control panel rather
than from the computer. “Offline” indicates that the printer is not “online” with the
computer.
Online
GL-3
Glossary
When the printer is online, it is ready to receive or is receiving commands from the
computer. The printer must be online to print.
Parallel Interface
A standard computer interface. Information is transferred between devices over
separate wires, allowing all of the bits that make up the character to be transmitted
simultaneously (in parallel).
Park Position
The position in which continuous forms paper is retracted or “parked” on the rear forms
tractors. When continuous forms paper is loaded, it moves forward from the park
position to the platen.
Permanent Memory
Memory that retains information even when power is turned off. The printer’s
permanent memory retains the default settings specified using the printer Set-Up
mode.
Pitch
Characters per horizontal inch (cpi).
Printing Test
A test that determines whether the printer is working correctly. Test pages are printed
to show print quality and verify whether all characters print. The printing test only tests
the printer. It does not test how the computer works with the printer.
Proportional Spacing
Character spacing in which wide characters occupy more space than do narrow
characters. For example, characters such as “W” or “M” occupy more horizontal space
than do characters such as “i” or “l.” Many soft fonts are proportionally spaced.
Sometimes designated PS, proportional spacing is the opposite of monospacing.
Resident Fonts
Fonts present (resident) in the printer’s permanent memory. For this printer, the
resident fonts are Courier 10, Prestige Elite 12, Pica 10, OCR-B 10, Boldface PS,
Compressed font, Correspondence, Draft, and High-speed Draft. Unlike soft fonts,
resident fonts can always be accessed.
Serial Interface
A standard computer interface. Information is transferred between devices over a
single wire (although other wires are used for control). A long cable is often necessary
in networking environments, where the printer may be shared.
Set-Up Mode
One of the printer’s two operating modes. In the Set-Up mode, the control panel can
be used to select the printer default settings, such as print features, hardware options,
and top-of-form. The Set-Up mode also provides some diagnostic functions. See also
Normal mode.
Shadow Printing
Shadow printing prints characters twice for emphasis. Characters printed the second
time are shifted slightly to the right.
Single Sheets
GL-4
Glossary
Single sheets are sheets of paper, envelopes, and noncontinuous multiple forms fed
into the printer using the cut sheet stand. Single sheets are also called cut sheets.
Soft Fonts
Fonts downloaded from a disk to the printer memory. Soft fonts are also referred to as
downloaded fonts. Unlike resident fonts, soft fonts are available only when in the
printer memory.
Software
Programs that control the computer and printer to perform specified tasks, such as
word processing, database management, and preparation of spreadsheets. Software
is sometimes referred to as application software.
Tear Bar
A cutting edge provided on the top cover to tear off continuous forms along the
perforation.
Top Margin
The total space at the top of the printed page. The top margin is the sum of the top-ofform setting, the software-specified top margin, and the printer’s TOP-MRGN setting in
Set-Up mode.
Top-of-Form (TOF)
The logical top of the physical page, as “understood” by the printer when loading
paper. The default TOF settings are 0 inch for both cut sheets and continuous forms.
Tractor Feed
A method for feeding continuous forms forward for printing. Holes on the sides of the
forms fit over sprockets on two tractors located inside the printer.
Unidirectional Printing
Printing is performed in one direction only, left to right. Unidirectional printing is slower
than bidirectional printing, but the vertical alignment is more accurate. Unidirectional
printing is useful when precise vertical alignment is required, as in ruled tables.
