Parallel Interface
The 8-bit parallel data interface supports IEEE 1284 bi-directional parallel
communications in nibble mode. The parallel interface provides a means of
communication that is typically faster than the previously mentioned 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.
Parallel Cabling Requirements
An IEEE-1284 compatible bi-directional 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
The table below shows the pin configuration and function of a standard
computer-to-printer parallel cable.
