Serial Port
The table below shows the pinout of the print server’s 9-pin RS-232 serial
port. The print server’s serial port is a DTE (Data Terminal Equipment)
port, and should be connected to a DCE (Data Communications Equipment)
serial port on your printer. Consult your printer’s documentation for
detailed information on how to connect the print server to your printer.
