Network Buffer Purpose: To configure the size of the network input buffer. Values: Auto* 3K to maximum size allowed Printer automatically calculates the Network Buffer size (recommended setting).

To maximize the range for the Network Buffer size, disable or reduce the size of the parallel, serial, infrared, LocalTalk, and USB buffers. Note: Changing the Network Buffer menu item automatically resets the printer. See also: Resource Save Network Setup Purpose: To configure an internal print server.
