Operator Controls
The QL 320 will come with one of two possible control panels.
The standard control panel is detailed below and in Figure 8. The
optional control panel (Figure 9) features an LCD which allows
easy display and selection of many printer functions and is detailed on following pages.
Standard Keypad
The standard keypad has three control buttons and two multipurpose indicators.
• The Power button turns the QL 320 on and off.
• The Feed button advances a length of media which is determined by the type of media being used. Label media will
be advanced to the next gap or bar sense marker. Journal
(plain) media will be advanced a length determined by the
printer’s software.
• The Function button is controlled by a printer’s specific application to support such functions as:
Print a battery Level reporting
Print the Local Area Network (LAN) status
Print a Short Range Radio Frequency (SRRF) status
Print a Media supply report
The green LED on the left side of the control panel indicates
the status of several printer features:
•A slowly blinking sequence indicates the printer’s battery
needs charging.
•Printers with a wireless QuickLink module installed: a quickly blinking sequence indicates the printer has not established a link to either a Local Area Network or a compatible
wireless equipped terminal.
•Printers with a wireless QuickLink module installed: A
steadily lit indicator shows that the printer has established a
wireless link, either to the LAN or to a compatible terminal.
A steadily lit green indicator on a non-wireless printer is a
power-on indicator.
The yellow LED on the right side of the control panel has two
indication conditions.
•A rapidly blinking yellow LED and a chime indicate that no
application has been loaded into the printer.
•Printers with a wireless QuickLink module installed: a rapidly blinking LED indicates normal data transmission.

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
reset” 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 insure
all elements of the print head are working, print out the version of
software loaded in the printer and then print two reports.
The first report indicates model, ROM version, serial number,
baud rate, etc. The second report prints out more detailed information on the printer’s configuration and parameter settings. If no
second report appears, there is no application loaded. (See the
Troubleshooting Section for a sample print-out and a further discission 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:
• By a cable between the printer and its host terminal
• Linking to a host terminal via Infrared (usually by means of
the industry standard IrDA protocol)
• By means of a Short Range Radio Frequency (SRRF) link.
• By means of a wireless LAN (Local Area Network). This
applies to QL 320N Network Printers only.
18 QL 320 User’s Guide
QL 320 User’s Guide 19
IR Communications
Printers equipped for infrared (IR) communications are identified
by a small “IR” logo on the unit’s label. IR allows wireless communications between the printer and the host terminal. IR units can
also communicate with a cable as detailed above, however, IR
functions are disabled when the cable is plugged in. QL 320 units
with the IR option can be configured to conform to the standard
IrDA communications protocol
Linking a Printer to an IrDA Host
IrDA compliant terminals will automatically initiate communications to the printer. First insure that there is a direct line of sight
between the printer and the terminal that will be sending data. The
IR window on the front of the QL 320 must face the corresponding
window on the terminal to properly send and receive signals. An
IrDA compliant terminal will seek out any linkable devices and establish communications between them, even turning the printer on
if necessary .

SRRF Communications
Both the printer and the device it communicates with must follow
either the Bluetooth standard or Zebra’s proprietar y SRRF protocol. The communications protocol is determined by the specific
QuickLink module installed in the printer.
Printers equipped for short range radio frequency communications (SRRF) allow wireless communication with their host terminals from any direction. Reliable transmission distances will vary
but usually exceed 1m. (39”) under worst conditions. SRRF printers can be identified by reading the printer’s model number label
on the front of the unit, which will show the radio module’s identification number and/or its operating frequency. QL 320 printers
equipped with a Bluetooth wireless module will have the Bluetooth
logo on the model number label.
Zebra SRRF Network Overview
Zebra’s short range RF network operates as a collection of
linked pairs of terminals and printers. There is no base station or
centralized control; control of the network is distributed across the
entire network.
Before SRRF operation can begin, the QL 320 must be “linked”
to a terminal with a compatible short-range radio. Linking means
that addresses are exchanged between the terminal and the printer. Once linked, the terminal and the printer become a “linked pair”
and communicate exclusively with each other. The terminal and
the printer can be turned on and off without affecting the link; it remains valid until another link is deliberately created. Thus it is not
necessary to perform a link every time that the equipment is used.
So long as the linked pair is kept together, they remain linked indefinitely. If the linked pair is not stored together, then the terminal
and printer selected should be linked prior to use.
Multiple linked pairs can be operated in close quarters and each
terminal will only communicate with its linked printer. Each SRRF
radio module has a unique device address (terminal or printer),
based on the device serial number.
Linking From the Terminal to the Printer
The linking operation can be activated from either the terminal
or the printer. If the terminal has a scanner available, then the barcoded serial number on the back of every printer can be scanned
and used to establish the printer’s unique address. Once the printer’s address is established, the terminal can then initiate a link to
that printer. If no scanner is available the user can manually enter
QL 320 User’s Guide 21
the serial number of the printer; however, this method is not recommended. The terminal can only capture the desired printer using this type of link.
The terminal must be programmed to guide the user through
scanning the printer serial number bar-code, then execute an algorithm which converts the serial number into an address. Zebra
can provide C source code to licensed OEM customers that handles the conversion from serial number to address.
Linking From the Printer to the Terminal
When no scanner is available, and/or no additional software is
to be written for the terminal, then the linking operation can be initiated solely by the printer.
In this procedure the printer broadcasts a message seeking an
available terminal. If a terminal “hears” the broadcast and is available, it will respond by linking to the printer.
To insure a secure link, the user must perform the link operation
far enough away from other operating terminals so that the printer
does not inadvertently capture some other user’s terminal. Any
other terminal that hears the broadcast message from the printer
may try to link to it, therefore you should insure that only one terminal is within broadcast range Feedback is available from the
printer as to the outcome of the link operation.

Bluetooth™ Networking Overview
Exposure to Radio Frequency Radiation
The radiated output power of this internal wireless
radio is far below the FCC radio frequency exposure
limits. Nevertheless, this Bluetooth radio must be used
in such a manner that the antenna is 2.5 cm or further
from the human body.
The radio and antenna are mounted internally in this
printer in such a way that, when the printer is used in a
standard configuration (belt clip, soft case, shoulder
strap), the 2.5 cm distance from the users body will be
met. Do not use the printer in an unauthorized manner.
The internal wireless radio operates within guidelines
found in radio frequency safety standards and
recommendations. The level of energy emitted is far
less than the electromagnetic energy emitted by
wireless devices such as mobile phones.
“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 (about 32 feet).
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
tion with another. The second device (the
then accepts or rejects the connection. A Bluetooth enabled QL
320 will normally act as a slave, but in theory any Bluetooth device can be either a master or a slave. This miniature network is
sometimes referred to as a “piconet” and can consist of several
Bluetooth enabled devices.
Each Bluetooth QL 320 has a unique Bluetooth Device Address
(BDA) loaded into its Quick Link module when manufactured.
A Typical Bluetooth Connection Sequence
In this simplified sequence “Joe’s Terminal” is a Bluetooth ready
hand held terminal running an application that needs access to a
printer.
1. Joe’s Terminal performs a search of its “piconet” (a Device In-

or the
client)

quiry) and determines that there are four Bluetooth devices in the
vicinity.
2. Joe’s Terminal queries each of the four nearby devices to determine which services they provide (a Service Discovery). The
Bluetooth enabled QL 320 “Sandy’s Printer” offers the printing service.
3. Joe’s Terminal sends a print connection request to Sandy’s
Printer.
4. Sandy’s Printer evaluates the request and determines that
Joe’s Terminal is permitted to use the print service,
correct password is submitted
.
but only if the
5. Sandy’s Printer queries Joe’s Terminal for the password (Authentication).
6. Joe’s Terminal returns the correct password and the print connection is established.
7. After Joe’s Terminal is finished printing it disconnects with
Sandy’s Printer. (Some Bluetooth services disconnect automatically, others must be closed manually.)
There are several layers of security in the Bluetooth system, so
this sequence may not be a completely accurate representation of
how your printer may function in a Bluetooth environment. For the
most part, communications using the Bluetooth protocol are initiated and processed without any operator intervention, much like
the IrDA system described previously.

Wireless Local Area Network (WLAN)
WARNING: Use of the QL 320 will result in
exposure to Radio Frequency radiation. To conform to
FCC RF exposure requirements the printer must be
used only in the intended orientation and in the
intended manner .
Printers equipped for Wireless Local Area Network (WLAN)
communications using the industry standard 802.11 or 802.11b
protocols are known as QL 320N Printers. These printers allow
wireless communication as a node within a local area network,
and its wireless capabilities allow communications from any point
within the LAN’s perimeter. Methods of establishing communications to the QL 320 will vary with each LAN application.
QL 320N printers can be identified the model number on the
front of the unit.
The QL 320N is designed for use with either a shoulder strap
and a specially designed soft case, or with a belt clip. The printer
should be oriented on the operator’s hip so that printed material is
transported
When the QL 320N is used as designed, either the printer’s soft
case or the belt clip will allow use of the printer in the manner
mandated by the FCC.

Setting Up the Software
The QL 320 uses Zebra’s CPL Programming language which
was designed for mobile printing applications. CPL is fully described in the Mobile Printing Systems Programming Manual,
which is available in Portable Document Format (.pdf) on-line
at Zebra’s website
You can also use Label Vista™, Zebra’s Windows™ based label
creation program which uses a graphical interface to create and
edit labels in the CPL language. Label Vista is available either online at Zebra’ s website, or on a CD (part number AC15065-1).
The QL 320 with its optional memory upgrade can support an
interpreter for ZPL II
desktop printers. To use ZPL II, refer to the ZPL II Programming
Guide. If you choose to use a third party label preparation system,

Preventive Maintenance
WARNING: To avoid possible personal injury or
damage to the printer, never insert any pointed or sharp
objects into the printer.
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.
• Choose the media that is easiest to “burn.” 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.
• Select Tear-Off mode whenever possible (Peel-Off mode
uses more power).
• If your printer has the optional LCD display: Use the display
backlight only when necessary. Turn it off whenever it is not
needed. The LCD backlight consumes a great deal of power.
• Pull the battery out of the printer 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.

Instructions on entering
Communications
Diagnostics (Dump) Mode.
Communications Diagnostics
If there’s a problem transferring data between the computer and
the printer, try putting the printer in the Communications Diagnostics Mode (also referred to as the “DUMP” mode). The printer will
print the ASCII characters and their and their text representation
(or the period ‘.’, if not a printable character) for any data received
from the host computer
To enter Communications Diagnostics Mode:
1. Print a configuration label as described on pg. 34.
5. At the end of 2nd diagnostics report, the printer will print:
“Press FEED key to enter DUMP mode”.
6. Press the FEED key. The printer will print: “Entering DUMP
mode”.
Note: If the FEED key is not pressed within 3 seconds, the printer will print “DUMP
mode not entered” and will resume normal operation.
7. At this point, the printer is in DUMP mode and will print the
ASCII hex codes of any data sent to it, and their text representation (or “.” if not a printable character).
Additionally, a file with a “.dmp” extension containing the ASCII
information will be created and stored in the printer’s memory. It
can be viewed, “cloned” or deleted using the Label Vista application. (Refer the Label Vista documentation for more information.)
To terminate the Communications Diagnostics Mode and return
the printer to normal operations:
1. Turn the printer OFF.
2. Wait 5 seconds.
3. Turn the printer ON.
Calling the Help Desk
If the printer fails to print the configuration label, or you encounter problems not covered in the Troubleshooting Guide, contact
the Help Desk. Help Desk addresses and phone numbers for
your area can be found in Appendix D of this manual. The Help
Desk will need the following information:
• Model number/type (e.g. QL 320)
• Unit serial number (Found on the large label on the back of
the printer, also found in the configuration label printout))
• Product Configuration Code (PCC) (15 digit number found
on the small label on the back of the unit)
