Parallel Port
When communicating via the parallel port, the values selected 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.
A standard 36-pin parallel connector (Figure 34) is available on the back of the printer for
connection to the data source.

Table 11 shows the pin configuration and function of a standard computer-to-printer parallel
