printer driver, make sure the driver is installed properly.
See your application program manual for instructions. Also
see your printer manual for additional instructions on
using your printer with application programs.

the test indicates an error, contact your printer dealer.
Option Card Problems
If you install an option card and it is not functioning properly,
check the following:
1. Is the option card installed correctly? The most common
problem with option cards is a loose connection. Make sure
the card is well seated in its slot. Check the installation
procedure described in Chapter 4 and also see the
instructions that come with the card.
2. Did you set the necessary DIP switches or jumpers on
the option card? See the card’s manual for instructions.
3. Did you set the necessary jumpers on the main system board?
See Chapter 4 for more information.
4. Did you run the SETUP program to update your
configuration after installing the card? See Chapter 2 of the
Setup Guide.
5. If you used the option card to add an external device to
your computer, did you use the proper cable to connect the
device to the cards connector on the back panel?
