Interfaces
4-35 Printer Configuration
Mode
The parallel interface supportsCentronics parallel communication as
well as IEEE 1284 bidirectional (two-way) parallel communication,
which provides five modes of operation: byte, compatibility, ECP
(enhanced compatibility port), EPP (enhanced parallel port), and
nibble. See chapter 5, “Additional Technical Information,” for a
discussion of the different modes.
Notes This value must be less than K Mem For Spool.
A 00000 value does not turn off the spooling buffer for the
parallel interface. If the value is set to 00000, the printer
calculates the Min K Spool automatically at initialization.
The printer must be restarted for changes to the Min K Spool
menu to take effect. You can either let the printer restart
automatically after you save the change and exit from the
configuration menu, or you can wait for the change to take
effect the next time you manually turn on the printer.
Menu Administration/Communications/Parallel/Mode
Choices Interactive—Establish bidirectional (IEEE 1284) parallel
communication between the host and the printer.
Noninteractive—Establish one-way (Centronics) parallel
communication from the host to the printer.
Disabled—Turn off parallel communication with the host. The
printer stops accepting print jobs over the parallel interface.
Default Noninteractive
Notes The printer must be restarted for changes to the menu to take
effect. You can either let the printer restart automatically after
you save the change and exit from the configuration menu, or
you can wait for the change to take effect the next time you
manually turn on the printer.
