Using printer menus Menu selection Serial Buffer Job Buffering Serial Protocol Robust XON Baud Data Bits Purpose Configures the size of the serial input buffer. Note: Changing the Serial Buffer menu item automatically resets the printer. Values Disabled Auto* 3K to maximum size allowed Temporarily stores jobs on the printer hard disk before printing. Note: Changing the Job Buffering menu item automatically resets the printer. Off* On Auto Selects the hardware and software handshaking values for the serial interface. DTR* DTR/DSR XON/XOFF XON/XOFF/DTR XONXOFF/DTRDSR Determines whether the printer Off* communicates availability to the computer. This menu item only applies to the serial On port if Serial Protocol is set to XON/ XOFF. Specifies the rate at which data can be received through the serial port. Note: 138200, 172800, 230400, and 345600 baud rates are displayed in the STANDARD SERIAL menu. These values are not displayed in the SERIAL OPTION 1, SERIAL OPTION 2, or SERIAL OPTION 3 menus. 1200 2400 4800 9600* 19200 38400 57600 115200 138200 172800 230400 345600 Specifies the number of data bits that 7 are sent in each transmission frame. 8* 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 the 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. 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. Hardware handshaking. Hardware handshaking. Software handshaking. Combined hardware and software handshaking. Combined hardware and software handshaking. Printer waits to receive data from the computer. Printer sends a continuous stream of XONs to the host computer to indicate that the serial port is ready to receive more data. 35
