Disabled
	• 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.

	menus causes the printer to restart. The menu selection is then updated.
