The following tables show the signal names that are present at the parallel and serial
sockets on your printer.
If you are having trouble selecting a cable that will work with your computer:
❐Show these tables to your computer hardware dealer.
❐Check the pin assignments of your computer’s printer port (parallel or serial, depend -
ing which one you are having problems with), and show that to your hardware
dealer as well.
In most circumstances, a normal cable will work.
