Parallel Data Port
The 8-bit parallel data interface supports IEEE 1284 bidirectional 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.

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.
