Purpose
Values
PCL SmartSwitch
Configures the printer so it
automatically switches to PCL
emulation when a print job
received through the serial
port requires it, regardless of
the default printer language.
On*
Off
On*—The printer examines the data at
the serial interface and selects PCL
emulation if the data indicates that is
the required printer language.
Off—The 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.
PS SmartSwitch
Configures the printer so it
automatically switches to
PostScript emulation when a
print job received through the
serial port requires it,
regardless of the default
printer language.
On*
Off
On*—The printer examines the data at
the serial interface and selects
PostScript emulation if the data
indicates that is the required printer
language.
Off—The 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.
On
Printer performs NPA processing. If
data is not in NPA format, it is rejected
as bad data.
Off
Printer does not perform NPA
processing.
Auto*
Printer examines the data to determine
the format and then processes it
appropriately.
Serial Buffer
Configures the size of the
serial input buffer.
Note: Changing the Serial
Buffer menu item
automatically resets the
printer.
Disabled
Disables job buffering. Any jobs already
buffered on the disk are printed before
normal processing of incoming jobs
resumes.
Auto*
Printer automatically calculates the
Serial Buffer size (recommended
setting).
3K to maximum
size allowed
User specifies the Serial 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
Serial Buffer size, disable or reduce the
size of the parallel and USB buffers.
Job Buffering
Temporarily stores jobs on the
printer hard disk before
printing.
Note: Changing the Job
Buffering menu item
automatically resets the
printer.
Off*
Does not buffer print jobs to the hard
disk.
On
Buffers print jobs to the hard disk.
Auto
Buffers print jobs only if the printer is
busy processing data from another
input port.
