Serial <X - Lexmark X850E Reference Manual

Menu item Purpose
Parallel Mode 2 Determines whether the parallel
port data is sampled on the leading
or trailing edge of strobe.
This menu item only appears when
the associated parallel port
supports this feature.
Mac Binary PS Configures the MFP to process
Macintosh binary PostScript print
jobs.
Serial <x>
Use these menu items to change printer settings affecting jobs sent to the MFP through an optional serial port.
Menu item Purpose
PCL Configures the MFP so it
SmartSwitch automatically switches to PCL
emulation when a print job received
through the serial 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 serial 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.

Samples parallel port data on the
leading edge of strobe.
Samples parallel port data on the
trailing edge of strobe.
The MFP processes raw binary
PostScript print jobs from computers
using the Macintosh operating system.
Note: This setting often causes
Windows print jobs to fail.
The MFP filters PostScript print jobs
using standard protocol.
The MFP processes print jobs from
computers using either Windows or
Macintosh operating systems.
On—The MFP examines the data at
the serial interface and selects PCL
emulation if the data indicates that is
the required printer language.
Off—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.
On—The MFP examines the data at
the serial interface and selects
PostScript emulation if the data
indicates that is the required printer
language.
Off—The MFP does not examine the
incoming data. The MFP uses PCL
emulation to process the job if PCL
SmartSwitch is On, or uses the default
printer language specified in the
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 the data to
determine the format and then
processes it appropriately.
