The printer also supports a Device ID function. When queried for its ID, the printer
returns the following information:
• Manufacturer
• Command set
• Model of printer
The LEXPARAL.EXE file is available from ftp.lexmark.com as /pub/driver/
technical_brief/LEXPARAL.EXE. Use your web browser to access ftp://

When the
Advanced Status menu item is set to On, the printer supports IEEE 1284
communication. If the attached host computer does not support IEEE 1284
communication, you can turn
Advanced Status to Off from the printer operator panel or
through MarkVision Professional, and SLCTIN* and AUTO FD XT* will be ignored.
Note: Excessive device queries and status checks (Nibble and Byte modes) will
slow printer performance.
You can get IEEE 1284 documentation by calling 1-800-678-IEEE (order number
DS02709).
Parallel Mode 1
Parallel Mode 1 is a feature available for many Lexmark printers. The factory default
setting is
On or Off depending on your printer model. See your printer documentation
for the factory default for your printer.
If the host side of the parallel interface is using open collector drivers to transmit data
to the printer,
Parallel Mode 1 should be set to Off to increase reliability of data transfer.
Turning this mode
Off equalizes all parallel interface signal impedances. On some
printer models, you can set
Parallel Mode 1 to Off from the printer operator panel,
through MarkVision Professional, or through a PJL command. See your printer
documentation for more information.
