Types of Connections

The method of connecting the printer to a data source depends on the communication options installed in the printer and the host. 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 Password Level 3 Parameters on page 65 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 PCs and other hosts.

•Advantages: Cables and connectors are readily available from computer equipment stores and suppliers; easy to connect; two-way communication between the host and the printer.

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