NPA Mode
To specify 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.
Parity
To select the parity for serial input and
output data frames.
Even
Odd
None*
Ignore
PCL
SmartSwitch
To configure 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* Printer examines data on the serial
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.
PS
SmartSwitch
To configure 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* Printer examines data on the serial
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.
Robust XON
To determine whether the printer
communicates availability to the
computer.
This menu item only applies to the
serial port if Serial Protocol is set to
XON/XOFF.
Off* Printer waits to receive data from the
computer.
On Printer sends a continuous stream of
XONs to the host computer to indicate
that the serial port is ready to receive
more data.
