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 [Print]. 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 and MS-DOS manuals 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.

7.Try running the Parallel port (printer interface) diagnostic test if you have a parallel printer, or the Serial port (RS-232C) test if you have a serial printer. Appendix C describes these tests. If the test indicates an error, contact your printer dealer.
