Using printer menus
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
(1K increments)
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.
Serial Protocol Selects the hardware and software
handshaking values for the serial
interface. *DTR Hardware handshaking.
DTR/DSR Hardware handshaking.
XON/XOFF Software handshaking.
XON/XOFF/DTR Combined hardware and software
handshaking.
XONXOFF/DTRDSR Combined hardware and software
handshaking.
Robust XON Determines 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.
