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.

Auto*

appropriately.

Note: Changing this menu item automatically resets the printer.

USB Buffer

Purpose:

To configure the size of the USB input buffer.

Values:

Disabled

Job buffering is disabled. Any jobs already buffered on the disk are

 

printed before normal processing of incoming jobs resumes.

Auto*

Printer automatically calculates the USB Buffer size (recommended

 

setting).

3K to maximum

User specifies the USB 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 USB Buffer size, disable or reduce the size of the parallel, serial,

 

and network buffers.
