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 command or the MENU utility. See your printer
manual and the MS-DOS Reference Manual
for more
details.
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.
Try running the Parallel Port (Printer Interface) check if
you have a parallel printer, or the Serial Port (RS-232C)
check if you have a serial printer. Appendix C describes
these diagnostics checks. If the diagnostics test indicates an
error, contact the place where you bought the printer.

Is the option card installed correctly? The most common
problem with option cards is a loose connection. Make sure

Did you set the necessary DIP switches or jumpers on the
option card? See your option card manual for instructions.
Did you set the necessary jumpers on the main system board?
See Chapter 6 for more information.
Did you run the Setup program to redefine your computer’s
configuration after installing the card? See Chapter 2.
