Parallel Buffer

Purpose:

To configure the size of the parallel input buffer.

Values:

Disabled	Disables the parallel port.
Auto*	Printer automatically calculates the Parallel Buffer size (recommended setting).
3K to maximum	User specifies the Parallel Buffer size. The maximum size depends on the
size allowed	amount of memory in your printer, the size of the other link buffers, and
	whether Resource Save is set to On or Off. To maximize the range for the
	Parallel Buffer size, disable or reduce the size of the serial, infrared, LocalTalk,
	and USB buffers.
