Parallel Port Basics and Interfacing SpringerLink . The PC parallel port uses three I/O addresses to transfer data through the port’s interface. Each address controls one byte of data, however, for two I/O addresses, several data bits are unused and a few other bits are inverted internally by the port circuitry. The first I/O address is used to output data only, the second address is used to input data through the port and the last address can be used to both input and output data.

USB "parallel port" adapters and cables generally aren't. They contain chips that emulate USB printers and send the print data out the parallel port like it might be sent to a similar printer.

If you have a computer with a CGA, EGA, VGA or Super VGA display card (most common for computers after 1990) the parallel port address is 378H (888 decimal). This address is important because we can then write appropriate.
