Plug one end of the parallel cable into the parallel port of your computer.
The parallel port should be labeled "Printer," "Parallel," "PRN," "LPT1," or
something similar.
Plug the other end of the parallel cable into the socket on the back of the
printer and secure it in place with the clips.
To connect with a serial cable
For connection to the serial interface, you will probably want to use a standard
RS-232C cable, like the one shown below.
Important!
• The following instructions apply to the serial cable that is suitable for use
with an IBM-compatible personal computer. Note that they do not apply to all
types of computers and cables. If you are unsure about what type of cable you
should use, consult your dealer.
• Make sure that the printer is unplugged from the AC outlet and that the
computer is switched off before connecting them.
