3.Connect the computer end of the parallel cable firmly into the parallel port on your computer and tighten the screws on the connector.
4.Turn on the computer and the printer. The printer Power light should come on.
5.Establish communication between the computer and the printer by sending the following DOS command:
MODE LPT1:,,P
For DOS 5.0 and DOS 6, send
MODE LPT1: RETRY=R
This command causes infinite retries when sending data so that the computer does not timeout while waiting for the printer to print. All data is directed to parallel port 1. If the printer is connected to a different interface port on the computer (such as parallel port 2), modify the Mode command.
Note: This DOS command can be added to the AUTOEXEC.BAT file so that it will not be necessary to type the command whenever the computer is turned on. Refer to your DOS manual for instructions on adding this command to the AUTOEXEC.BAT file.
