Parallel Menu (continued) Menu item NPA Mode Parallel Buffer * Factory default Printer setting = On = Off = Auto* NPA is a mode of bidirectional communication that follows the conventions defined in Network Printing Alliance Protocol, a Printer/Host Control Specification developed by the NPA. NPA mode requires special processing of the print data. If NPA Mode is set to On, the data received must be in NPA format. If not, it is rejected as bad data. If NPA Mode is set to Off, the printer does not perform any NPA processing. If NPA Mode is set to Auto, the printer examines the data to determine the format and then processes it in either format. The NPA Mode setting in the Parallel Menu applies only to the parallel interface connection. Note: Changing the NPA Mode setting automatically resets the printer. = Disabled = Auto* = 3K to maximum size allowed You can configure the size of the parallel input buffer to meet the requirements of your system. The maximum size available for modification 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, you can disable or reduce the size of the serial, infrared, LocalTalk, and Universal Serial Bus (USB) buffers. Choose Auto to calculate a buffer size proportional to the total amount of available printer memory. In most cases, Auto is the recommended setting. Note: Changing the Parallel Buffer setting automatically resets the printer. Changing printer settings 69
