To connect with a parallel cable
For connection to the parallel interface, you will probably want to use a standard
parallel cable, like the one shown below.
Note:
In addition to using the parallel interface as-is to connect a parallel interface,
you can also connect an optional serial-to-parallel converter (page 40) to
convert serial data from the computer to parallel data. This effectively provides
two serial interfaces for connection of separate computers.
Important!
The following instructions apply to the Centronics parallel 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.
For an IBM-compatible personal computer:
Use a standard 36-pin Centronics parallel cable.
The parallel cable should be no longer than six feet (two meters). Longer
cables can result in poor transfer of information.
Important!
Make sure that the printer is unplugged from the AC outlet and that the
computer is turned off before connecting them.
