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.
1. 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. Check Chapter 1 of
this manual or see your printer manual for instructions on
how to connect your printer to the computer.
Also make sure your printer has paper in it, since many
printers cannot operate without paper.
2. 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.
3. If you are using more than one parallel port or more than
one serial port, the DIP switches on the computer must he
set properly so MS-DOS knows which one is the primary
port and which is the secondary port. See Appendix A for
instructions.
