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 computer in response to a "Printer Status
Request" command is sent through the RS-232 serial port. However, if the
host computer has a properly configured IEEE-1284 parallel port that is
recognized by the printer, status information is returned through the
parallel port. Port selection for status information is determined each time
the printer is turned on.
