Parallel Printer Cable
This cable can be used to connect a parallel printer to the parallel port on a PC. The phrase parallel cable can be ambigous as it shelters numerous different specifications, not all of which are simple PC to printer type. The parallel port socket on a computer uses 25 pins. There are two types of parallel printer cable that are widely used for PCs. The old "standard" IBM Printer cable and the newer IEEE 1284 bi-directional cable commonly sold today.
