20 QL 420 User’s GuideVerify the Printer Is WorkingBefore you connect the printer to your computer or portabledata terminal, make sure that the printer is in proper working or-der. 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 Label1. Turn the printer off. Load the media compartment withjournal media (media with no black bars printed on theback)2. Press and hold the Feed Button.3. Press and release the Power button and keep the Feedbutton pressed. When printing starts, release the Feedbutton. The unit will print a line of interlocking “x” characters to en-sure all elements of the print head are working, print out the ver-sion 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 in-formation on the printer’s configuration and parameter settings.If no second report appears, there is no application loaded. (Seethe Troubleshooting Section for a sample print-out and a furtherdiscission on how to use the configuration label as a diagnostictool.)Connecting the PrinterThe printer must establish communications with a host terminalwhich sends the data to be printed. Communications occur infour basic 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 Bluetooth™ short range radio frequencylink.•By means of a wireless LAN (Local Area Network) per802.11b specifications.
QL 420 User’s Guide 21Cable Communications CAUTION. The power should be turned off beforeconnecting or disconnecting the communications cable.All QL 420 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 plugsinto the serial communications port on the side of the QL 420printer, which is protected by a weather resistant flap. The con-nector is keyed to assure correct alignment; do not try to forcethe cable if it does not plug in. The other end of the cable mustbe plugged into the host terminal as shown in Figure 11, or to aserial port on a computer (Figure 12.) Communications betweenthe terminal and the printer are controlled by the applicationsrunning on the terminal and the printer.FIGURE 12: COMMUNICATIONS WITH A P.C.Communications Cable to TerminalPart number varies. Refer to Appendix A.QL 420CommunicationsPort FIGURE 11: CABLE COMMUNICATIONSSerial Communications Cable toComputerRefer to Appendix A for part numbers.
22 QL 420 User’s GuideIR CommunicationsPrinters equipped for infrared (IR) communications are identi-fied by a small “IR” logo on the unit’s label. IR allows wirelesscommunications between the printer and the host terminal. IRunits can also communicate with a cable as detailed above, how-ever, IR functions are disabled when the cable is plugged in. QL420 units with the IR option can be configured to conform to thestandard IrDA communications protocolLinking a Printer to an IrDA HostIrDA compliant terminals will automatically initiate communica-tions to the printer. First ensure that there is a direct line of sightbetween the printer and the terminal that will be sending data.The IR window on the front of the QL 420 must face the corre-sponding window on the terminal to properly send and receivesignals. An IrDA compliant terminal will seek out any linkable de-vices and establish communications between them, even turningthe printer on if necessary.FIGURE 13: IR COMMUNICATIONSArea of IR Window1M (39”)
QL 420 User’s Guide 23Wireless Communications with Bluetooth™using ZBRRadioThe following section only applies when the Bluetooth Module (FCC ID: I28MD-BTC2-E)is installed in the QL 420 printer (note that only one of the radio options can be in-stalled in the printer at one time).“Bluetooth” is a worldwide standard for the exchange of databetween two devices via radio frequencies. Bluetooth radios arerelatively low powered to help prevent interference with other de-vices running at similar radio frequencies. This limits the rangeof a Bluetooth device to about 10 meters (about 32 feet).Both the printer and the device it communicates with must fol-low the Bluetooth standard. Exposure to Radio Frequency RadiationThe radiated output power of this internal Bluetooth radio is farbelow the FCC radio frequency exposure limits. Nevertheless,this Bluetooth radio must be used in such a manner that theantenna is 2.5 cm or further from the human body.The radio and antenna are mounted internally in this printersuch that when the printer is worn with the back of the printeragainst the body and the front of the printer (where paper exits)away from the body, then the 2.5 cm distance between theantenna and the users body will be met. Do not use the printerin an unauthorized manner.The internal Bluetooth radio operates within guidelines found inradio frequency safety standards and recommendations. Thelevel of energy emitted is far less than the electromagneticenergy emitted by other wireless devices such as mobilephones.European Regulatory Information for this RadioAUS B DK FINFDGRIREILUX NL PESUKNote: -Member states in the EU with restrictive use for this device arecrossed out!This device is also authorized for use in all EFTA member states (CH, ICE,LI, NOR) 0682 Important Notice:This device is a portable RF printer intended forcommercial and industrial use in all EU andEFTA member states except in France whererestrictive use applies.

Bluetooth software is always run-ning in the background, ready to respond to connection requests.One device (known as the master or the client) must request aconnection with another. The second device (the slave or theserver) then accepts or rejects the connection. A Bluetooth en-abled QL 420 will normally act as a slave, but in theory any Blue-tooth device can be either a master or a slave. This miniaturenetwork is sometimes referred to as a “piconet” and can consistof several Bluetooth enabled devices.Each Bluetooth QL 420 has a unique Bluetooth Device Address(BDA) loaded into its QuickLink module when manufactured.For the most part, communications using the Bluetooth protocolare initiated and processed without any operator intervention,much like the IrDA system described previously.
QL 420 User’s Guide 27Wireless Local Area Network (WLAN) Module Using CFRadioThe following section only applies when the CF (Compact Flash) WLAN module (WithFCC ID: I28MD-QL4137) is installed in the QL 420 printer (note that only one of theradio options can be installed in the printer at one time). The FCC ID number label ison the front of the module and can be read with the module installed. WARNING: Use of the QL 420 with the radio module marked“with FCC ID: I28MD-QL4137” meets the FCC requirements forradio frequency (RF) radiation exposure in the standard bodyworn configuration with no minimum separation.
