Values
Off Printer performs NPA processing. If
data is not in NPA format, it is rejected
as bad data.
On Printer does not perform NPA
processing.

the format and then processes it
appropriately.
On* Printer examines the data on the USB
interface and selects PCL emulation if
the data indicates that is the required
printer language.
Off 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.
On* Printer examines data on the USB
interface and selects
PostScript emulation if the data
indicates that is the required printer

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.
Disabled Job buffering is disabled. Any jobs
already buffered on the disk are
printed before normal processing of
