Understanding the printer menus		154
	Use	To
	PS SmartSwitch	Set the printer to automatically switch to PS emulation when a print job received
	On	through a serial port requires it, regardless of the default printer language.
	Off	Notes:
		• On is the factory default setting.
		• When set to Off, the printer does not examine incoming data. The printer uses
		PCL emulation if PCL SmartSwitch is set to On. It uses the default printer
		language specified in the Setup menu if PCL SmartSwitch is set to Off.
	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.
		• 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	Set the size of the parallel input buffer.
	Disabled	Notes:
	Auto
		• Auto is the factory default setting.
	3K to [maximum size allowed]
		• 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 store 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	Enable bidirectional communication through the parallel port.
	On	Notes:
	Off
		• On is the factory default setting.
		• Off disables parallel port negotiation.
