Connecting a parallel cable

Use the parallel port when directly connecting the printer to a personal computer.

CAUTION: Make sure that the printer is turned off before connecting the parallel cable.
NOTE: To ensure reliability, use an IEEE-1284 compliant parallel cable (these cables are clearly marked with “IEEE-1284”). Only IEEE-1284 cables support all of the printer’s advanced features.
  1. Connect the parallel cable to the parallel port.

    The cable should install easily. If installation is difficult, check the cable orientation.

  2. Snap the wire clips in place to secure the cable to the printer.
