Unlike the serial port, 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 you system has a 25-pin, DB25 connector (see picture below).
