If the printer is so equipped, rotate the Belt Clip to allow ac-cess to the Battery compartment.2. Insert the battery into the printer as shown in Figure 2,3. Rock the Battery into the printer as shown until it locks inplace.When the battery is first installed, the Control Panel indicatorsmay briefly turn on and then go off which indicates the battery isnot fully charged (see “Charging the Battery” below and “OperatorControls”).Charging the BatteryRefer to Figure 3. Your battery charger may look slightly differ-ent from the ones illustrated.If you are using the LI 72 battery charger:1. Install the battery in the printer and plug the Charger intothe appropriate A.C. wall receptacle. Then insert thecharge cable into the battery charger jack.2. The charger LED will indicate the status of the charger asfollows:• A steady light indicates the battery is undergoing a fastcharge.•A slow blinking light indicates the charger is in trickle mode.The battery is ready for use.•A rapidly blinking light indicates a problem with the battery.The battery may have an internal short, or its charge moni-toring circuitry may be malfunctioning. The battery shouldnot be used any further.•Battery Packs may be charged either when installed in theprinter or when removed. Do not attempt to charge batteries with the LI 72while printing. Attempting to print while charging canresult in improperly charged batteries.

10 QL 320 User’s GuideLoading the MediaYou can operate this printer in one of two different modes: Tear-Off or Peel-Off. Tear-Off mode allows you to tear off each label (ora strip of labels) after it is printed. In Peel-Off mode, the backingmaterial is peeled away from the label as it is printed. After youremove this label, the next one is printed.Installing the Media1. Refer to Figure 4. Open the printer:•Rotate the latch release levers on each side of the printeras shown at “1” below.The latch assembly willflip open automaticallyas shown at “2”.•Rotate the mediaCover back asshown at “3”, ex-posing the mediacompartmentand the adjust-able mediasupports.FIGURE 4Media SupportsMediaCompartment

18 QL 320 User’s GuideVerify the Printer Is WorkingBefore you connect the printer to your computer or portable dataterminal, make sure that the printer is in proper working order.You can do this by printing a configuration label using the “two keyreset” method. If you can’t get this label to print, refer to “Trouble-shooting”.Printing a Configuration Label1. Turn the printer off. Load the media compartment with jour-nal 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 but-ton pressed. When printing starts, release the Feed button. The unit will print a line of interlocking “x” characters to insureall elements of the print head are working, print out the version ofsoftware 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 infor-mation on the printer’s configuration and parameter settings. If nosecond report appears, there is no application loaded. (see theTroubleshooting Section for a further discission on the how to usethe configuration label as a diagnostic tool.)Connecting the PrinterThe printer must establish communications with a host terminalwhich sends the data to be printed. Communications occur in fourbasic ways:•By a cable between the printer and its host terminal•Linking to a host terminal via Infrared (usually by means ofthe industry standard IrDA protocol)•By means of a Short Range Radio Frequency (SRRF) link.•By means of a wireless LAN (Local Area Network). Thisapplies to QL 320N Network Printers only.

QL 320 User’s Guide 19Cable Communications CAUTION. The power should be turned offbefore connecting or disconnecting thecommunications cable.All QL 320 printers can communicate by cable; the specific ca-ble supplied with your printer will vary with the host terminal. The8- pin circular connector on your communications cable plugs intothe serial communications port on the side of the QL 320 printer.It is keyed to assure correct alignment; do not try to force it if itdoes not plug in. The other end of the cable must be plugged intothe host terminal as shown in Figure 10, or to a serial port on acomputer (Figure 11.) Communications between the terminal andthe printer are controlled by the applications running on the termi-nal and the printer.FIGURE 11Communications Cable to TerminalPart number varies. Refer to Appendix A.QL 320Communications PortFIGURE 10Serial Communications Cable to ComputerRefer to Appendix A for part numbers.

QL 320 User’s Guide 21SRRF CommunicationsBoth the printer and the device it communicates with must followeither the Bluetooth standard or Zebra’s proprietary SRRF proto-col. The communications protocol is determined by the specificQuickLink module installed in the printer.Printers equipped for short range radio frequency communica-tions (SRRF) allow wireless communication with their host termi-nals from any direction. Reliable transmission distances will varybut usually exceed 1m. (39”) under worst conditions. SRRF print-ers can be identified by reading the printer’s model number labelon the front of the unit, which will show the radio module’s identifi-cation number and/or its operating frequency. QL 320 printersequipped with a Bluetooth wireless module will have the Bluetoothlogo on the model number label.Zebra SRRF Network OverviewZebra’s short range RF network operates as a collection oflinked pairs of terminals and printers. There is no base station orcentralized control; control of the network is distributed across theentire network.Before SRRF operation can begin, the QL 320 must be “linked”to a terminal with a compatible short-range radio. Linking meansthat addresses are exchanged between the terminal and the print-er. Once linked, the terminal and the printer become a “linked pair”and communicate exclusively with each other. The terminal andthe printer can be turned on and off without affecting the link; it re-mains valid until another link is deliberately created. Thus it is notnecessary to perform a link every time that the equipment is used.So long as the linked pair is kept together, they remain linked in-definitely. If the linked pair is not stored together, then the terminaland printer selected should be linked prior to use.Multiple linked pairs can be operated in close quarters and eachterminal will only communicate with its linked printer. Each SRRFradio module has a unique device address (terminal or printer),based on the device serial number.Linking From the Terminal to the PrinterThe linking operation can be activated from either the terminalor the printer. If the terminal has a scanner available, then the bar-coded serial number on the back of every printer can be scannedand used to establish the printer’s unique address. Once the print-er’s address is established, the terminal can then initiate a link tothat printer. If no scanner is available the user can manually enter

22 QL 320 User’s Guidethe serial number of the printer; however, this method is not rec-ommended. The terminal can only capture the desired printer us-ing this type of link.The terminal must be programmed to guide the user throughscanning the printer serial number bar-code, then execute an al-gorithm which converts the serial number into an address. Zebracan provide C source code to licensed OEM customers that han-dles the conversion from serial number to address.Linking From the Printer to the TerminalWhen no scanner is available, and/or no additional software isto be written for the terminal, then the linking operation can be ini-tiated solely by the printer.In this procedure the printer broadcasts a message seeking anavailable terminal. If a terminal “hears” the broadcast and is avail-able, it will respond by linking to the printer.To insure a secure link, the user must perform the link operationfar enough away from other operating terminals so that the printerdoes not inadvertently capture some other user’s terminal. Anyother terminal that hears the broadcast message from the printermay try to link to it, therefore you should insure that only one ter-minal is within broadcast range Feedback is available from theprinter as to the outcome of the link operation.

QL 320 User’s Guide 23Bluetooth™ Networking Overview Exposure to Radio Frequency RadiationThe radiated output power of this internal wirelessradio is far below the FCC radio frequency exposurelimits. Nevertheless, this Bluetooth radio must be usedin such a manner that the antenna is 2.5 cm or furtherfrom the human body.The radio and antenna are mounted internally in thisprinter in such a way that, when the printer is used in astandard configuration (belt clip, soft case, shoulderstrap), the 2.5 cm distance from the users body will bemet. Do not use the printer in an unauthorized manner.The internal wireless radio operates within guidelinesfound in radio frequency safety standards andrecommendations. The level of energy emitted is farless than the electromagnetic energy emitted bywireless devices such as mobile phones.“Bluetooth” is a worldwide standard for the exchange of data be-tween two devices via radio frequencies. Bluetooth radios are rel-atively low powered to help prevent interference with otherdevices running at similar radio frequencies. This limits the rangeof a Bluetooth device to about 10 meters (about 32 feet). In order to exchange data, two Bluetooth enabled devices mustestablish a connection. Bluetooth software is always running inthe background, ready to respond to connection requests. Onedevice (known as the master or the client) must request a connec-tion with another. The second device (the slave or the server)then accepts or rejects the connection. A Bluetooth enabled QL320 will normally act as a slave, but in theory any Bluetooth de-vice can be either a master or a slave. This miniature network issometimes referred to as a “piconet” and in theory can consist ofseveral 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 SequenceIn this simplified sequence “Joe’s Terminal” is a Bluetooth-awarehand held terminal running an application that needs access to aprinter.1. Joe’s Terminal performs a search of its “piconet” (a Device In-

24 QL 320 User’s Guidequiry) and determines that there are four Bluetooth devices in thevicinity.2. Joe’s Terminal queries each of the four nearby devices to de-termine which services they provide (a Service Discovery). TheBluetooth enabled QL 320 “Sandy’s Printer” offers the printing ser-vice.3. Joe’s Terminal sends a print connection request to Sandy’sPrinter.4. Sandy’s Printer evaluates the request and determines thatJoe’s Terminal is permitted to use the print service, but only if thecorrect password is submitted.5. Sandy’s Printer queries Joe’s Terminal for the password (Au-thentication).6. Joe’s Terminal returns the correct password and the print con-nection is established.7. After Joe’s Terminal is finished printing it disconnects withSandy’s Printer. (Some Bluetooth services disconnect automati-cally, others must be closed manually.)There are several layers of security in the Bluetooth system, sothis sequence may not be a completely accurate representation ofhow your printer may function in a Bluetooth environment. For themost part, communications using the Bluetooth protocol are initi-ated and processed without any operator intervention, much likethe IrDA system described previously.

QL 320 User’s Guide 25Wireless Local Area Network (WLAN) WARNING: Use of the QL 320 will result inexposure to Radio Frequency radiation. To conform toFCC RF exposure requirements the printer must beused only in the intended orientation and in theintended manner.Printers equipped for Wireless Local Area Network (WLAN)communications using the industry standard 802.11 or 802.11bprotocols are known as QL 320N Printers. These printers allowwireless communication as a node within a local area network,and its wireless capabilities allow communications from any pointwithin the LAN’s perimeter. Methods of establishing communica-tions to the QL 320 will vary with each LAN application.QL 320N printers can be identified the model number on thefront of the unit.The QL 320N is designed for use with either a shoulder strapand a specially designed soft case, or with a belt clip. The printershould be oriented on the operator’s hip so that printed material istransported away from the operator.When the QL 320N is used as designed, either the printer’s softcase or the belt clip will allow use of the printer in the mannermandated by the FCC.

26 QL 320 User’s GuideSetting Up the SoftwareThe QL 320 uses Zebra’s CPL Programming language whichwas designed for mobile printing applications. CPL is fully de-scribed in the Mobile Printing Systems Programming Manual,which is available in Portable Document Format (.pdf) either on-line at Zebra’s website, or on a 3.5” floppy disk (part numberDISK-PROMAN).You can also use Label Vista™, Zebra’s Windows™ based labelcreation program which uses a graphical interface to create andedit labels in the CPL language. Label Vista is available either on-line at Zebra’s website, or on a CD (part number AC15065-1).The QL 320 with its optional memory upgrade can support ZPLII, the programming language used by Zebra desktop printers. Touse ZPL II, refer to the ZPL II Programming Guide. If you chooseto use a third party label preparation system, follow the installationinstructions included in the package.

QL 320 User’s Guide 29Preventive Maintenance WARNING: To avoid possible personal injury ordamage to the printer, never insert any pointed or sharpobjects into the printer.Extending Battery Life•Never expose the battery to direct sunlight or temperaturesover 104∞ F (40∞ C).•Always use a Zebra charger designed specifically for Li-thium-Ion batteries. Use of any other kind of charger maydamage the battery.•Choose the media that is easiest to “burn.” An authorizedZebra re-seller can help you determine the optimum mediafor your application.•If you print the same text or graphic on every label, consid-er using a pre-printed label.•Choose the correct print darkness, and print speed for yourmedia.•Use software handshaking (XON/XOFF) whenever possi-ble.•Select Tear-Off mode whenever possible (Peel-Off modeuses more power).•If your printer has the optional LCD display: Use the displaybacklight only when necessary. Turn it off whenever it is notneeded. The LCD backlight consumes a great deal of pow-er.•Pull the battery out of the printer if the printer won’t be usedfor a day or more and you’re not performing a maintenancecharge.•Consider purchasing an extra battery.•Remember that any rechargeable battery will lose its abilityto maintain a charge over time. It can only be recharged afinite number of times before it must be replaced.
