Use the following procedure to connect your printer to your host via
the serial port:
1 Insert the 25-pin male printer end of the cable into the
printer's serial port (see illustration above), then tighten the
screws on the cable to attach it to the printer.
2 Attach the other end of the cable to the host's serial port (see
illustration above).
On some hosts, the 25-pin parallel port and the 25-pin serial port
may look similar, but the parallel port is female and the serial port
is male.
