through a USB port requires it, regardless of the default printer language
Notes:

NPA Mode
Auto
On
Off
Sets the printer to perform the special processing required for bidirectional
communication following the conventions defined by the NPA protocol
Notes:
• Auto is the factory default setting. Auto sets the printer to examine data,
determine the format, and then process it appropriately.
• Changing this setting from the printer control panel and then exiting the menus
causes the printer to restart. The menu selection is then updated.
USB Buffer
Auto
3KB to [maximum size allowed]
Disabled
Sets the size of the USB input buffer
Notes:
• Auto is the factory default setting.
• Disabled turns off job buffering. Any jobs already buffered on the printer hard
disk are printed before normal processing resumes.
• The USB buffer size value can be changed in 1-KB increments.
• The maximum size allowed depends on the amount of memory in the printer,
the size of the other link buffers, and whether Resource Save is set to On or Off.
• To increase the maximum size range for the USB Buffer, disable or reduce the
size of the parallel, serial, and network buffers.
• Changing this setting from the printer control panel and then exiting the menus
causes the printer to restart. The menu selection is then updated.
