Standard Parallel Or Parallel <X - Lexmark X646ef Menus And Messages Manual

Standard Parallel or Parallel <x>
Use these menu items to change printer settings affecting jobs sent to the MFP through a parallel port, either Std Parallel or
Parallel <x>, where x represents 1 or 2.
Menu item Purpose
PCL Configures the MFP so it
SmartSwitch automatically switches to
PCL emulation when a print job
received through the parallel port
requires it, regardless of the default
printer language.
PS SmartSwitch Configures the MFP so it
automatically switches to PostScript
emulation when a print job received
through the parallel port requires it,
regardless of the default printer
language.
NPA Mode Specifies whether the MFP
performs the special processing
required for bidirectional
communication, following the
conventions defined in the Network
Printing Alliance (NPA) Protocol.
Note: Changing this menu item
automatically resets the MFP. It is
reset to configure memory, and any
permanent resources, such as fonts
or macros, are lost.
Parallel Buffer Configures the size of the parallel
input buffer.

The MFP examines data on the
parallel interface and selects
PCL emulation if the data indicates
that is the required printer language.
The MFP does not examine the
incoming data. The MFP 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.

The MFP does not examine the
incoming data. The MFP uses PCL

SmartSwitch is On, or uses the default

Setup Menu if PCL SmartSwitch is
Off.
The MFP performs NPA processing. If
data is not in NPA format, it is rejected
as bad data.
The MFP does not perform NPA
processing.
The MFP examines data, determines
the format, and then processes it
appropriately.
Disables job buffering. Any jobs
already buffered on the hard disk are
printed before normal processing of
incoming jobs resumes.
The MFP automatically calculates the
Parallel Buffer size (recommended
setting).
The user specifies the Parallel Buffer
size. The maximum size depends on
the amount of memory in the MFP, 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.
