serial port, you may see error 1101.
1. If your printer does not work at all, 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 instructions.
2. Check the printer’s DIP switch or control panel settings.
These settings help a printer communicate properly with
the computer. See your printer manual for the correct
settings.

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.
