Standard Network and Network <x>
Use this menu selection to change printer settings affecting jobs sent to the printer through a network port (either Standard Network or
Network <x>).
Menu selection Purpose
PCL SmartSwitch Configures the printer so it automatically
switches to PCL emulation when a print
job received through the network port
requires it, regardless of the default
printer language.
PS SmartSwitch Configures the printer so it automatically
switches to PostScript emulation when a
print job received through the network
port requires it, regardless of the default
printer language.
NPA Mode Specifies whether the printer 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 printer.
Network Buffer Configures the size of the network input
buffer.
Note: Changing the Network Buffer
menu item automatically resets the
printer.
Job Buffering Temporarily stores jobs on the printer
hard disk before printing.
Note: Changing this menu item
automatically resets the printer.

Printer examines data on the network
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.
Printer examines data on the network
interface connection and selects
PostScript emulation if the data indicates
that is the required printer language.
Printer does not examine the incoming
data. The printer 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 printer will not perform any NPA
processing.
Printer examines the incoming data to
determine the format. If the incoming data
is not NPA packets, the information is
passed to the printer as non-NPA.
Printer automatically calculates the
Network Buffer size (recommended
setting).
User specifies the Network 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 Network Buffer size, disable or reduce
the size of the parallel, serial, and USB
buffers.
Does not buffer 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.
