3.1.2 Interface Connection
The printer can be connected to the host via the parallel, USB, serial, or optional network interface. The printer will
automatically connect to the first port that delivers valid data. Once established, the printer’s power must be cycled ‘Off’
and ‘On’ to change an interface connection.
The Parallel Connection needs a Centronics
IEEE 1284 cable with a
36-pin male connector for unidirectional (forward channel)
communications, or an IEEE 1284 Compliant cable for bi-directional
communications (forward and reverse channels). Also, for bi-directional
communications your host must have supporting software. See Section 5
for more information.
The USB Connection needs a USB cable and is supported in
Windows
95 and greater operating systems. Depending upon the
operating system of your host computer, installation requirements may
differ slightly.
The Serial Connection needs a serial interface cable with specific pin-
outs for proper communications (part numbers and pin-outs are given,
below; contact your reseller to order). The interface supports RS-232C
communications via a DB-9 connector. Serial port settings are menu-
selectable and must match your host’s serial port settings; see Section 4,
for non-display printers or Section 5 for display-equipped printers.

The Optional Internal Ethernet Print Server is available only for display-equipped printers. When using this
