Printer Problems
Below are some general steps to follow if you are having
difficulty with your printer. If the problem persists and you need
more detailed information, check your printer manual. You may
see one of the following error messages:
9 0 1 Parallel port error
1101 Serial port error.
These error messages appear if you are having trouble with the
port to which your printer is connected. If it is connected to the
parallel port, you may see error number 901; if your printer uses
the serial port, you may see error number 1101.

If your printer does not work correctly immediately after you
install it, check that the printer has power and is properly
connected to the computer. (Also, make sure your printer
has paper in it.) See Chapter 1 or your printer manual for
instruct ions.
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.
If you are using more than one parallel port or more than
one serial 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 Setup program.
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 Shift and press Print Screen. This should print the
contents of the screen on your printer.
