Menu selection Purpose
PS SmartSwitch Configures the printer so it
automatically switches to
PostScript emulation when a
print job received through the
USB 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.
USB Buffer Configures the size of the USB
input buffer.
Note: Changing the USB Buffer
menu item automatically resets
the printer.
Job Buffering Temporarily stores jobs on the
printer hard disk before printing.
Mac Binary PS Configures the printer to
process Macintosh binary
PostScript print jobs.

Printer examines data on the USB
interface 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 it uses the
default printer language specified in
the Setup Menu if PCL SmartSwitch
is Off.
Printer performs NPA processing. If
data is not in NPA format, it is rejected
as bad data.
Printer does not perform NPA
processing.
Printer examines the data to
determine the format and then
processes it appropriately.
Job buffering is disabled. Any jobs
already buffered on the disk are
printed before normal processing of
incoming jobs resumes.
Printer automatically calculates the
USB Buffer size (recommended
setting).
User specifies the USB 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
USB Buffer size, disable or reduce the
size of the parallel, serial, and
network buffers.
Does not buffer print 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.
Printer processes raw binary
PostScript print jobs from computers
using the Macintosh operating
system.
Note: This setting often causes
Windows print jobs to fail.
Printer filters PostScript print jobs
using standard protocol.
Printer processes print jobs from
computers using either Windows or
Macintosh operating systems.
