Parallel Interface

The printer is also available with an IEEE-1284 parallel interface. The printer configuration must be set to the parallel interface using the printer’s Configuration Menu described in the “Diagnostics and Configuration” section of the A794 Service Guide.

IEEE Bi-directional Parallel Connector

The following illustration shows the parallel communication connector and pin assignments. The connector is located at the rear of the printer, and is designated as an IEEE 1284-A receptacle, commonly known as a D-Subminiature 25 pin.
