Parallel Data Port

Parallel Data Port
The parallel data interface supports IEEE 1284 bidirectional parallel communications in nibble
mode. The parallel interface provides a means of communication that typically is faster than
the serial interface methods. In this method, the bits of data that make up a character are sent
all at one time over several wires in the cable, one bit per wire.
When communicating via the parallel port, the values selected on the printer must be the same
as those used by the host equipment connected to the printer. Port selection for status
information is determined by the channel sending the request. The parallel port can be set for
bidirectional or unidirectional communication. The default setting is bidirectional.
Parallel Cabling Requirements
See Connect the Printer to the Computer or Network on page 30 for basic cabling information.
A standard 36-pin parallel connector is available on the back of the printer for connection to
the data source. An IEEE-1284 compatible bidirectional parallel data cable is required when
this communication method is used. The required cable must have a standard 36-pin parallel
connector on one end that is plugged into the mating connector located at the rear of the
printer. The other end of the cable connects to the printer connector at the host computer. Port
selection for status information is determined each time the printer is turned on.
Parallel Port Interconnections
Table 20 shows the pin configuration and function of a standard computer-to-printer parallel
cable.

The maximum current draw may be limited by option
configuration.
To enable this capability, a qualified service technician
must install a jumper on the printer’s main logic board on
JP1, pins 2 and 3.
