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

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 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.
