NPA is a mode of bidirectional communication that follows the
conventions defined in Network Printing Alliance Protocol, a
Printer/Host Control Specification developed by the NPA. NPA
mode requires special processing of the print data.
If NPA Mode is set to On, the data received must be in NPA
format. If not, it is rejected as bad data. If NPA Mode is set to
Off, the printer does not perform any NPA processing. If NPA
Mode is set to Auto, the printer examines the data to determine
the format and then processes it in either format.
The NPA Mode setting in the Parallel Menu applies only to the
parallel interface connection.
Note: Changing the NPA Mode setting automatically resets the
printer.

You can configure the size of the parallel input buffer to meet
the requirements of your system.
The maximum size available for modification depends on the
amount of memory in your printer, the size of the other link
buffers, and whether Resource Save is set to On or Off. To
maximize the range for the Parallel Buffer size, you can disable
or reduce the size of the serial, infrared, LocalTalk, and
Universal Serial Bus (USB) buffers.
Choose Auto to calculate a buffer size proportional to the total
amount of available printer memory. In most cases, Auto is the
recommended setting.
Note: Changing the Parallel Buffer setting automatically resets
the printer.
