IfNPA 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 NPAprocessing. If NPA Mode
is set to Auto, the printer examines the data to determine the format and then processes it in
either format.

3K to maximumsize allowed
Youcan configure the size of the parallel input bufferto meet the requirements of your system.
Them aximumsize available for modification depends on the amount of memory in your

maximizethe range for the parallel buffer size, you can disable or reduce the size of theser ial,
network, infrared,LocalTalk, and Universal Serial Bus (USB) buffers.
