Standard Network and Network <x>
Use these menu items to change printer settings affecting jobs sent to the printer through a network port (either Standard
Network or Network <x>).
Menu item Purpose
PCL Configures the printer so it
SmartSwitch 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.
Printer does not perform NPA
processing.
Printer examines the data to
determine the format and then
processes it appropriately.
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.
