Soft Keys
Programmable LCD Settings
In addition to the status icons, the LCD control panel can display
other printer settings and functions as text. Applications can be written to allow the user to view and /or modify these settings using the
scroll and select keys on the display. The menu that comes with the
printer provides access to the most commonly used parameters. Refer
to the CPCL Programming Manual for a complete list of the parameters, and for details on how to change the front panel display (p/n
PROMAN-CPCL at www.zebra.com/manuals).
The LCD backlighting option allows viewing of the screen in a dark
environment, or provides better contrast in a very bright environment. The QLn320 can be programmed to enter a low power mode
(Backlight Off) during periods of front panel inactivity. While in low
power mode, the screen is populated with menus and status icons,
data which may or may not be readable depending on ambient light
conditions.
The QLn320 provides a configurable time delay from the time the
backlight is turned on to when it turns off. The time range for this delay is 5 to 1200 seconds with a default time of 10 seconds. The backlight can be activated within one second after any of the cursor, select,
or soft keys is pressed. (The feed button does not activate the backlight.) The status bar icons, the user space content, and the navigation
bar will remain on the screen with the backlight off.
Extensive use of the display backlight will decrease the time
the printer can run between charges. Refer to the section
“Extending Battery Life” for more information.

Verify the Printer Is Working
Before you connect the printer to your computer or portable data
terminal, make sure that the printer is in proper working order. You
can do this by printing a configuration label using the “two key” method. If you can’t get this label to print, refer to “Troubleshooting”.
Printing a Configuration Label
1. Turn the printer off. Load the media compartment with
journal media (media with no black bars printed on the
back)
2. Press and hold the Feed Button.
3. Press and release the Power button and keep the Feed
button pressed. When printing starts, release the Feed
button.
The unit will print a line of interlocking “x” characters to
ensure all elements of the print head are working, print out the
version of software loaded in the printer and then print two reports.
The report indicates model, serial number, baud rate, and more
detailed information on the printer’s configuration and parameter settings. (See the Troubleshooting Section for sample printouts and a further discussion on how to use the configuration label as a diagnostic
tool.)
Connecting the Printer
The printer must establish communications with a host terminal which sends the data to be printed. Communications
occur in four basic ways:
• QLn320 printers can communicate by cable via either RS-232C or
USB 2.0 protocols. USB drivers are included in the Zebra Designer
Driver which can be downloaded from www.zebra.com/drivers.
• By means of a Bluetooth™ short range radio frequency link.
(Optional)
• By means of a wireless LAN (Local Area Network) per 802.11 specifications. (Optional)
• By means of the Ethernet when docked on the Ethernet cradle.
(Optional)

Cable Communication
Caution • The printer should be turned off before connecting or
disconnecting a communications cable.
The QLn320 printer can communicate by cable; the specific
cable supplied with your printer will vary with the host terminal and your model printer.
RS-232C Communications
The 14-pin serial connector on your communications cable plugs
into the serial communications port on the side of the printer. QLn320
model printers also have a USB port.
USB Communications
The small 5-pin connector on the USB cable plugs into the
printer. The connectors are keyed to assure correct alignment; do not try to force the cable if it does not plug in. The

other end of the cable must be plugged into the host terminal
as shown in Figure 18, or to a serial or USB port on a computer (Figure 18). The QLn320 series is configured with the USB
Open HCI interface driver allowing it to communicate with
Windows® based devices.
USB drivers are included in the Zebra Designer Driver which can be
downloaded from the Zebra Web site. Other terminals or communications devices may require the installation of special drivers to use the
USB connection. Consult the factory for further details.
Providing Strain Relief for Communications Cable
If you are connecting either a USB or RS-232 communications cable
to the printer permanently, access the communications port on the
side of the printer next to the latch release lever. Plug the connector
into the appropriate port and align the plastic locking cap with the cut
outs shown below. Rotate the locking cap clockwise to lock the cable
in place. (Turn counterclockwise to unlock the cable.) Once locked in
place, this provides strain relief for the cable and will prevent the cable
from disconnecting from the printer.
Note: Only one cable can be present in the USB/RS-232

Wireless Communications with Bluetooth™
Bluetooth is a worldwide standard for the exchange of data between two devices via radio frequencies. Bluetooth radios are
relatively low powered to help prevent interference with other devices running at similar radio frequencies. This limits the range of a
Bluetooth device to about 10 meters (32 feet). Both the printer and
the device it communicates with must follow the Bluetooth standard.
Other than conditions specified elsewhere in this manual, only one of
the radio options can be installed in the printer at one time and the
antenna used for these transmitters must not be co-located or must
not operate in conjunction with any other antenna.
Bluetooth Networking Overview
Each Bluetooth enabled QLn320 printer is identified by a unique
Bluetooth Device Address (BDA). In order to exchange data, two
Bluetooth enabled devices must establish a connection.
Bluetooth software is always running in the background,
ready to respond to connection requests. One device (known
as the master or the client) must request a connection with another. The second device (the slave or the server) then accepts
or rejects the connection. A Bluetooth enabled QLn320 printer will normally act as a slave creating a miniature network
with the terminal sometimes referred to as a “piconet”.
For the most part, communications using the Bluetooth protocol are initiated and processed without any operator intervention.

WLAN Overview
QLn320 printers can be equipped with a radio using the industry standard 802.11 protocols. They will have the FCC ID
number on the serial number label on the back of the unit.
• QLn320 series Wireless Network Printers with the Zebra 802.11
WLAN radio module can be identified by the text “Wireless
Network Printer” on the serial number label on the back of the
printer.
• These printers allow wireless communication as a node within a
local area network (LAN) and its wireless capabilities allow communications from any point within the LAN’s perimeter. Methods
of establishing communications to the printer will vary with
each LAN application.
General information on establishing WLAN communications can be
found in either the ”CPCL Programming Manual” or the “Quick Start
Guide for Mobile Wireless Printers” both available on-line. More information and LAN configuration utilities are included in Zebra’s Net
Bridge™ program (version 2.8 and later). Net Bridge may be downloaded from the Zebra Web site.
Setting Up the Software
QLn320 printers use Zebra’s CPCL and ZPL Programming languages
which were designed for mobile printing applications. CPCL and ZPL
are fully described in the ”CPCL Programming Manual” and the “ZPL
Programming Guide” available on-line at www.zebra.com/manuals.
You can also use Designer Pro, Zebra’s Windows® based label creation program which uses a graphical interface to create and edit labels in the CPCL language.
Refer to Appendix F for tips on downloading the Designer Pro application from Zebra’s Web site.

Preventive Maintenance
Extending Battery Life
• Never expose the battery to direct sunlight or temperatures over 104° F (40° C).
• Always use a Zebra charger designed specifically for Lithium-Ion
batteries. Use of any other kind of charger may damage the battery.
• Use the correct media for your printing requirements. An
authorized Zebra re-seller can help you determine the optimum media for your application.
• If you print the same text or graphic on every label, consider using a pre-printed label.
• Choose the correct print darkness, and print speed for
your media.
• Use software handshaking (XON/XOFF) whenever possible.
• Remove the battery if the printer won’t be used for a day or more
and you’re not performing a maintenance charge.
• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its
ability to maintain a charge over time. It can only be recharged a finite number of times before it must be replaced. Always dispose of batteries properly. Refer to
Appendix E for more information on battery disposal.
