Printing at full-rated speed may require either an RS-422 or parallel
connection for wide format printing applications.
RS-232 Serial Interface Connector Pin Assignments
The printer provides a 25-pin DB-25S connector inside the lower
cabinet for connection of a serial interface cable. This connector is
also used for the RS-422 serial interface. Selection of the desired
interface is determined by the position of the RS-232/422 switch
located inside the lower cabinet of the printer.
The following table lists the pin assignments of the RS-232
interface connector.
