Types of Connections
The method of connecting the print engine to a data source depends on the communication
options installed in the print engine 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 Table 6, Print Engine Parameters on page 55 to configure these parameters.
When communicating via the parallel 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
print engine.
• Disadvantages: Slower than the parallel connection; limited to 50 feet (15.24 m) of cable.
