Communication cables

According to your printer configuration, the printer has different communication connection options. Select and attach
either 9-pin RS-232C, 25-pin RS-232C, standard USB, powered USB, or Ethernet communication cable to the printer and
host computer.
For printers with both 9-pin RS-232C and USB connectors, only a single communication connection is to be used during
operations.
