RS-232 Serial Interface

NOTE: The RS-232 serial interface circuit characteristics are compatible with
The RS-232 serial interface enables the printer to operate with bit serial
devices that are compatible with an RS-232 controller. The input serial data
transfer rate (in baud) is selectable from the printer's control panel. Baud rates
of 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 baud
rates are available.
The length of the data cable from the host computer to the printer must not
exceed 50 feet (15 meters) for RS-232.
