.NPA mode requires special processing of the print data.
If NPAMode is set to On, the data received must be in NPA format. If not, it is rejected as

NPAMode is set to Auto, the printer examines the data to determine the format and then

The maximumsize 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
maximizethe range for the USB buffer size, you can disable or reduce the size of the
parallel,ser ial, network, infrared, and LocalTalkbuffers.
