2.Check the printer manual for the printer’s correct DIP switch or control panel settings. These settings help a printer communicate properly with the computer.

3.If you are using more than one serial or parallel port, the computer must know which port is the primary port and which is the secondary port. See Chapter 2 for instructions on how to set the parallel and serial ports using the Peripherals Setup option in SETUP program.

4.If your printer is properly set up but is still not functioning, test it from the MS-DOS level. When the screen displays the

MS-DOS command prompt (such as C : \ or A: \), hold

down and press This should print the contents of the screen on your printer.

If it does not, you may need to change the internal setting of the computer’s parallel port for a parallel printer (or serial port for a serial printer). To do this, use the MS-DOS MODE or SETMODE command. See your printer manual and MS-DOS documentation for more details.

5.Many application programs (such as word processors) must be set up properly before they can use a printer. Check your program manual to see what customizing may be required.

6.If you are using an application program that requires a printer driver, make sure the correct driver is installed. See your application program manual for instructions. Also see your printer manual for additional instructions on using your printer with application programs.
