8-7 Interfaces Parallel Interface Use the Lexmark 3.04 m (10 ft) parallel cable part number 1329605, Lexmark 6.1 m (20 ft) parallel cable part number 1427498, or a cable that is IEEE 1284 compliant, to connect your printer to a personal computer or to a host system with a Centronicscompatible parallel port. Use the Lexmark 3.04 m (10 ft) parallel cable part number 43H5171 to connect your printer to a personal computer or to a host system with a Centronics-compatible parallel port using the optional parallel connector available once the parallel/USB interface option card is installed. Refer to your printer user documentation for the location of the printer parallel connector. Note: To reset your printer with an INIT* signal, set Honor Init to On from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. Your printer can communicate with a computer across the parallel interface in three ways: Computer to Printer This is typically how a computer and printer communicate. When the printer is receiving data from the computer, it can use either Standard or Fastbytes protocol. The burst transfer rate in Fastbytes is faster than in Standard protocol. For best throughput, use Fastbytes protocol. Printer to Computer (Advanced Status) Your printer can send data to the computer. This capability lets the printer send status messages to the computer on the parallel interface. Parallel Modes 1 and 2 These are printer features that enhance reliability of data transfer from the host computer to the printer. See "Parallel Mode 1" and "Parallel Mode 2" on page 8-20 for more information.

Parallel Interface
Use the Lexmark 3.04 m (10 ft) parallel cable part number 1329605, Lexmark 6.1 m
(20 ft) parallel cable part number 1427498, or a cable that is IEEE 1284 compliant, to
connect your printer to a personal computer or to a host system with a Centronics-
compatible parallel port. Use the Lexmark 3.04 m (10 ft) parallel cable part number
43H5171 to connect your printer to a personal computer or to a host system with a
Centronics-compatible parallel port using the optional parallel connector available
once the parallel/USB interface option card is installed. Refer to your printer user
documentation for the location of the printer parallel connector.
Note:
To reset your printer with an INIT* signal, set
Honor Init
to
On
from the printer
operator panel or through MarkVision Professional. Refer to your printer user
documentation for more information.
Your printer can communicate with a computer across the parallel interface in three
ways:
Computer to Printer
This is typically how a computer and printer communicate. When the printer is
receiving data from the computer, it can use either
Standard
or
Fastbytes
protocol.
The burst transfer rate in Fastbytes is faster than in Standard protocol. For best
throughput, use Fastbytes protocol.
Printer to Computer (Advanced Status)
Your printer can send data to the computer. This capability lets the printer send status
messages to the computer on the parallel interface.
Parallel Modes 1 and 2
These are printer features that enhance reliability of data transfer from the host
computer to the printer. See “Parallel Mode 1” and “Parallel Mode 2” on page 8-20
for more information.
