Menu Item Purpose
Parallel To configure the size of the parallel
input buffer.
Buffer
Note: Changing this menu item
automatically resets the printer.
Parallel To control the pull-up resistors on
the parallel port signals. This menu
Mode 1
item is useful for personal
computers that have open collector
outputs on the parallel port signals.
Parallel To determine whether the parallel
port data is sampled on the
Mode 2
leading or trailing edge of strobe.
PCL To configure the printer so it
automatically switches to
SmartSwitch
PCL emulation when a print job
requires it. This print job is
received through the parallel port,
regardless of the default printer
language.
PS To configure the printer so it
automatically switches to
SmartSwitch
PostScript emulation when a print
job received through the parallel
port requires it, regardless of the
default printer language.

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 your
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.
Disables the resistors.
Enables the resistors.
Samples parallel port data on the
leading edge of strobe.
Samples parallel port data on the
trailing edge of strobe.
Printer examines data on the
parallel interface and selects
PCL emulation if the data indicates
that is the required printer
language.
Printer does not examine the
incoming data. The printer uses
PostScript emulation to process
the job if PS SmartSwitch is On, or
uses the default printer language
specified in the Setup Menu if PS
SmartSwitch is Off.
