Menu selection Purpose
Parallel Buffer Configures the size of the
parallel input buffer.
Note: Changing this menu item
automatically resets the printer.
Job Buffering Temporarily stores jobs on the
printer hard disk before printing.
Advanced Status Enables bidirectional
communication through the
parallel port.
Protocol Specifies the parallel interface
protocol.
Honor Init Determines whether the printer
honors hardware initialization
requests from the computer.
The computer requests
initialization by activating the
INIT signal on the parallel
interface. Many personal
computers activate the INIT
signal each time the computer is
turned on and off.
Parallel Mode 2 Determines whether the parallel
port data is sampled on the
leading or trailing edge of
strobe.

Disables job buffering. Any jobs
already buffered on the disk are
printed before normal processing of
incoming jobs resumes.
Printer automatically calculates the
Parallel Buffer size (recommended
setting).
User specifies the Parallel Buffer size.
The maximum size depends on the
amount of memory in the printer, the
size of the other link buffers, and
whether Resource Save is set to On
or Off. To maximize the range for the
Parallel Buffer size, disable or reduce
the size of the serial and USB buffers.
Does not buffer print jobs to the hard
disk.
Buffers print jobs to the hard disk.
Buffers print jobs only if the printer is
busy processing data from another
input port.
Disables parallel port negotiation.
Enables bidirectional communication
through the parallel interface.
May resolve some parallel interface
problems.
Provides compatibility with most
existing parallel interface
implementations (recommended
setting).
Printer does not honor hardware
initialization requests from the
computer.
Printer honors hardware initialization
requests from the computer.
Samples parallel port data on the
leading edge of strobe.
Samples parallel port data on the
trailing edge of strobe.
