The method of connecting the printer to a data source depends on the communication options 
installed in the printer and the host computer. This section provides basic information about 
common interfaces.

When communicating via the serial data port (RS-232), the baud rate, number of data and stop 
bits, the parity, and the XON/XOFF or DTR control should be set to match those of the host 
computer. See 

 to configure these parameters. When 

communicating via the parallel port or the USB port, the previously mentioned parameters do 
not apply.

RS-232 Serial  A serial communication method consisting of data and control signals; 
available as a standard feature on most personal computers and other hosts.

• Advantages: Cables and connectors are readily available from computer equipment stores 

and suppliers; easy to connect; two-way communication between the computer and the 
printer; relatively long cable length.

• Disadvantages: Slower than the parallel connection; limited to 50 feet (15.24 m) of cable; 

may need to change printer parameters to match host computer; need to use a null-modem 
adaptor to connect to the printer if using a standard modem cable.

Null-modem adaptor (if using a standard modem cable)

9-pin male connector, connected to printer or null-modem adaptor

9-pin female connector, connected to computer

25-pin female connector, connected to computer

Maximum cable length = 50 ft. (15 m)
