If your printer supports parallel communications, the parallel port is IEEE-1284 or Centronics® mode. You can set which mode to use by changing a DIP switch or by using the control panel.

Refer to your Operator’s Handbook for DIP switch settings and control panel information. The communication settings are automatically configured for you. There are no operator settings required. We recommend waiting at least two seconds (or longer) when switching between the serial and parallel ports to send data, because data may be lost. Be careful when using print spoolers, because data transmission occurs in the background of the operating system. This makes data transmission completion difficult to determine when switching between ports.

You can use the autobaud feature to automatically set the printer’s baud rate, parity, data bits, and stop bits to match the host’s. Autobaud overrides the DIP switch settings and the values in the communication settings packet.

Do not send any data to the printer before using autobaud. The 9850 printer does not support autobaud.

To use autobaud, you must:

1.Power up the host first and then turn on the printer. Autobaud only works during the initial power up. Wait 2 to 5 seconds.

2.After the 9800 series printer’s power LED comes on (or the 9403 printer displays "Print Mode READY"), send a sequence of 32 alternating @A characters (for a total of 64 characters) to the printer.
