Parallel Data Port
A standard 36-pin parallel connector is available at the rear of the printer for
connection to the data source. Under normal circumstances, data sent from
the printer to the host in response to a “Printer Status Request” command is
sent through the RS-232 serial port. However, if the host has a properly
configured IEEE-1284 parallel port that is recognized by the printer, status
information will be returned through the parallel port. Port selection for
status information is determined each time the printer is turned on.
Parallel Port Interconnections
The following table shows the pin configuration and function of a standard
computer-to-printer parallel cable.
