Type	Commonly Used for	Communication	Printer Connector
		Protocol	Type
Standard Centronics	Most PC systems today	Bidirectional	36-pin male
Parallel† Cable		(Centronics standard)
Standard Serial‡ Cable	PCs and modems	RS-232C	25-pin male
		or
		RS-422A

†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.

Parallel Interface 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
