Understanding printer menus		107
	Use	To
	NPA Mode	Set the printer to perform the special processing required for bidirectional
	On	communication following the conventions defined by the NPA protocol.
	Off	Notes:
	Auto	• Auto is the factory default setting. Auto sets the printer to examine data,
		determine the format, and then processes it appropriately.
		• When set to On, the printer performs NPA processing. If the data is not in NPA
		format, it is rejected as bad data.
		• When set to Off, the printer does not perform NPA processing.
		• Changing this setting from the printer control panel and then exiting the
		menus causes the printer to restart. The menu selection is then updated.
	Serial Buffer	Set the size of the serial input buffer.
	Disabled	Notes:
	Auto
		• Auto is the factory default setting.
	3K to [maximum size allowed]
		• Disabled 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‑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 Serial 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.
	Job Buffering	Temporarily store print jobs on the printer hard disk before printing.
	Off	Notes:
	On
		• Off is the factory default setting. The printer does not buffer print jobs on the
	Auto
		printer hard disk.
		• 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.
	Protocol	Select the hardware and software handshaking settings for the serial port.
	DTR	Notes:
	DTR/DSR
		• DTR is the factory default setting.
	XON/XOFF
		• DTR/DSR is a hardware handshaking setting.
	XON/XOFF/DTR
	XONXOFF/DTRDSR	• XON/XOFF is a software handshaking setting.
		• XON/XOFF/DTR and XON/XOFF/DTR/DSR are combined hardware and
		software handshaking settings.
