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 MFP once
the menus are exited. It is reset to
configure memory, and any
permanent resources, such as fonts
or macros, are lost.

data is not in NPA format, it is rejected
as bad data.

processing.

determine the format and then
processes it appropriately.

3KB to maximum size
allowed
(1KB increments)

size. The maximum size depends on
the amount of memory in the MFP, the
size of the other link buffers, and

Off. To maximize the range for the USB
Buffer size, disable or reduce the size
of the parallel, serial, and network
buffers.

Macintosh binary PostScript print
jobs.
