Setting the Communication Parameters
If you are using the printer’s serial port to transfer data, you will need to make sure that the printer and the computer have identical communication parameter settings. To initialize the communication parameters for the printer:
•Press and hold the Feed key until the Fault light blinks three (3) times in a row. Release the key. The baud rate for the printer will be reset to 9600 baud, 8 bit word length, no parity, and 1 stop bit. Then, set the communications parameters on your computer to match this.
•If you need to use different settings than the defaults (for example, if you are using a modem with certain requirements) you have two options for setting the communications parameters. Send the ^SC “Set Commu- nications” ZPL command (described below) at 9600 baud via the serial port set up as shown above, then reset the computer to the new values. Or, send the ^SC command via the parallel port, then reconnect for serial port operation as needed.
