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 Network Menu applies only to the
network interface connection.
Note: Changing the NPA Mode setting automatically resets the
printer.

You can configure the size of the network buffer to meet the
requirements of your system. If the limited size of the input
buffer is preventing you from continuing work in your application
each time you send a job to the printer, you may want to
increase the buffer size.
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 Network Buffer size, you can disable
or reduce the size of the parallel, serial, infrared, LocalTalk, and
USB buffers.
Choose Auto to let the printer calculate the buffer size propor-
tional to the total amount of available printer memory. In most
cases, Auto is the recommended setting.
Note: Changing the Network Buffer setting automatically
resets the printer.
