Understanding printer menus		111
	Menu item	Description
	NPA Mode	Sets the printer to perform the special processing required for bidirectional
	Auto	communication following the conventions defined by the NPA protocol
	On	Notes:
	Off	• Auto is the factory default setting.
		• Changing this setting from the printer control panel and then exiting the
		menus causes the printer to restart. The menu selection is then updated.
	Parallel Buffer	Sets the size of the parallel input buffer
	Auto	Notes:
	3KB to [maximum size allowed]
		• Auto is the factory default setting.
	Disabled
		• Disabled turns off job buffering. Any print jobs already buffered on the printer
		hard disk are printed before normal processing resumes.
		• The parallel buffer size setting 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 Parallel Buffer, disable or reduce
		the size of the USB, 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.
	Job Buffering	Temporarily stores print jobs on the printer hard disk before printing
	Off	Notes:
	On
		• Off is the factory default setting.
	Auto
		• On buffers print jobs on the printer hard disk.
		• Auto buffers print jobs only if the printer is busy processing data from another
		input port.
		• Changing this setting from the printer control panel and then exiting the
		menus causes the printer to restart. The menu selection is then updated.
	Advanced Status	Enables bidirectional communication through the parallel port
	On	Notes:
	Off
		• On is the factory default setting.
		• Off disables parallel port negotiation.
	Protocol	Specifies the parallel port protocol
	Fastbytes	Notes:
	Standard
		• Fastbytes is the factory default setting. It provides compatibility with most
		existing parallel ports and is the recommended setting.
		• Standard tries to resolve parallel port communication problems.
