On

Auto
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.
•When the On setting is used, the printer performs NPA processing. If the data
is not in NPA format, it is rejected as bad data.
•When the Off setting is used, the printer does not perform NPA processing.
•When the Auto setting is used, the printer examines data, determines the
format, and then processes it appropriately.
•Changing this setting from the printer control panel and then exiting the menus
causes the printer to restart. The menu selection is updated.
Serial Buffer
Disabled
Auto
3K to <maximum size allowed>
Sets the size of the serial input buffer
Notes:
•Auto is the factory default setting.
•The Disabled setting turns off job buffering. Any jobs already buffered on the
disk are printed before normal processing is resumed.
•The serial buffer size setting can be changed in 1-K 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 Serial Buffer, disable or reduce the
size of the parallel, USB, 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 updated.
