Page 260 highlights

Using the printer menus Serial Buffer Purpose: To configure the size of the serial input buffer. Values: Disabled Auto* 3K to maximum size allowed Disables job buffering. Any jobs already buffered on the disk are printed before normal processing of incoming jobs resumes. Printer automatically calculates the Serial Buffer size (recommended setting). User specifies the Serial 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 Serial Buffer size, disable or reduce the size of the parallel and USB buffers. Note: Changing the Serial Buffer menu item automatically resets the printer. See also: Resource Save Job Buffering Purpose: To temporarily store jobs on the printer hard disk before printing. Values: Off* On Auto Does not buffer print jobs to the hard disk. Buffers print jobs to the hard disk. Buffers print jobs only if the printer is busy processing data from another input port. Note: Changing the Job Buffering menu item automatically resets the printer. Serial Protocol Purpose: To select the hardware and software handshaking values for the serial interface. 260
