Using printer menus
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

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.
RS-232/
RS-422
To specify the type of serial
communication.
Note: Selecting RS-422
automatically sets Serial Protocol
to XON/XOFF.
RS-232* Sets serial communication to
RS-232.
RS-422 Sets serial communication to
RS-422.
