Serial Interface

The serial connection is a standard connector for serial port interfaces and
requires a standard serial cable and a serial port available on the host
computer. You can use a serial cable length of 10 feet to 50 feet (3 to 15
meters).
RS-232-C Serial Interface
The printer provides a standard RS-232-C 25-pin connector for a serial port
interface. Most IBM-compatible computers have a serial port, designated
COM1, that has a 25-pin connector.
Table 5-6 lists the 25-pin designations and associated signals for serial
communications.
