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 Off Auto* Printer performs NPA processing. If data is not in NPA format, it is rejected as bad data. Printer does not perform NPA processing. 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 Auto* 3K to maximum size allowed Disables the parallel port. Printer automatically calculates the Parallel Buffer size (recommended setting). User specifies the Parallel Buffer size. The maximum size depends on the 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. Note: Changing the Parallel Buffer menu item automatically resets the printer. See also: Resource Save 243
