Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics port,
the parallel port is almost exclusively used with printers. The
parallel port on your system has a 25-pin, DB 25 connector(see
picture below).
