Connecting the Printer to a PC
You can connect the printer to either a serial (COM) port or a parallel port on your PC.
You must provide the correct cables for connecting the printer. Contact your Intermec
representative for ordering assistance if you do not have the appropriate cables.
Connecting the Printer to a PC Serial Port
To connect the 4420 or 4440 to your PC serial port, you need a shielded EIA
RS-232, RS-422, or RS-485 electrical interface with a 25-pin D-style subminiature
connector. You can purchase the Intermec serial 9F-25M null modem cable (Part No.
048693) or purchase a compatible cable from your local computer store.
Currently, Intermec does not offer a cable for the RS-422 interface. However, you will
find a schematic in Appendix C that you can use to purchase or make your own cable.
Also see Appendix C for the RS-232, RS-422, and RS-485 serial port assignments.
To connect the printer to a PC serial port
1. Turn off the printer.
2. Plug the 25-pin connector into the serial communications port on the rear of the
printer.
3. Plug the other end of the cable into a serial port on the PC.
4. If necessary, change the PC serial port configuration to match the printer. See
“Configuring the Serial Port for Communications” later in this chapter for more
information.
Connecting the Printer to a PC Parallel Port
If you are using a parallel port to communicate with the printer, you need a parallel
cable to run between the printer and the PC. You can purchase the Intermec IEEE 1284
parallel cable (Part No. 590124) or purchase a compatible cable from your local
computer store.
To connect the printer to a PC parallel port
1. Turn off the printer.
2. Plug the parallel interface connector into the parallel communications port on the
rear of the printer.
3. Plug the other end of the cable into a parallel port on the PC.
