Using printer menus
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
On* Printer examines data on the USB interface
and selects PostScript emulation if the data
indicates that is the required printer
language.
Off 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.
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.
Off The printer will not perform any NPA
processing.
On All data received by the printer must be in
NPA packets. Any non-packet data
received will be rejected as bad.
Auto* 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.
USB Buffer Configures the size of the USB input
buffer
Note: Changing the USB Buffer menu
item automatically resets the printer.
Disabled Job buffering is disabled. Any jobs already
buffered on the disk are printed before
normal processing of incoming jobs
resumes.
Auto* Printer automatically calculates the USB
Buffer size (recommended setting).
3K to maximum size
allowed
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, and network buffers.
Mac Binary PS Configures the printer to process
Macintosh binary PostScript print jobs
Off Printer processes raw binary PostScript
print jobs from computers using the
Macintosh operating system.
Note: This setting often causes Windows
print jobs to fail.
On Printer filters PostScript print jobs using
standard protocol.
Auto* Printer processes print jobs from
computers using either Windows or
Macintosh operating systems.
