Connect the parallel interface cable as described below:
1. Make sure both the printer and computer are turned off; then
plug the cable connector securely into the printer's parallel
interface connector. Squeeze the wire clips together until
they lock in place on either side of the connector.
Note:
If
your cable has a ground wire, connect it to the ground connector
beside the in interface connector.
2. Plug the other end of the cable into the computer. (If there is
a ground wire at the computer end of the cable, attach it to
the ground connector at the back of the computer.)
