Lexmark 812 manual Parallel Buffer, Parallel Mode, NPA Mode, Purpose, Values, See also

NPA Mode

Purpose:

To specify whether the printer performs the special processing required for bidirectional communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol.

Values:

On	Printer performs NPA processing. If data is not in NPA format, it is rejected as bad data.
Off	Printer does not perform NPA processing.
Auto*	Printer examines data and determines the format and then processes it appropriately.

Note: Changing this menu item automatically resets the printer.

Parallel Buffer

Purpose:

To configure the size of the parallel input buffer.

Values:

Disabled	Disables serial (Parallel, USB) port. Any jobs already buffered on the disk are
	printed before normal processing of incoming jobs resumes.
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 and USB buffers.

Note: Changing the Parallel Buffer menu item automatically resets the printer.
