Figure A.2 shows parallel and serial interface information to
help you obtain the correct printer cable.
Today most single-user computer systems (IBM PC and
compatibles) utilize the parallel interface because it allows
more data at a time to be transferred from the computer to the
printer than does a serial interface. If the printer is not
connected to a network, printing through the parallel
interface is most desirable.
The printers support a bidirectional parallel port, compatible
with the IEEE standard 1284-B, with forward transfer rates of
100 KBytes or 1 MBytes.
The FAULT signal (pin no. 32) goes true (low) under the
following conditions:
•
Off-line mode selected
•
Cover open (interlock open)
•
Paper out
•
Paper jam
•
Any machine fault
† Xerox has certified Parallel cables with these printers at a maximum of 6 feet.
‡ Xerox has certified Serial cables with these printers at a maximum of 4 feet.
