A parallel port is a computer interface used to connect printers and other devices to the input/output (I/O) panel on the back of a motherboard. Some computers and motherboards no longer include a parallel port, as universal serial bus (USB) has replaced the parallel port.
Even if your computer doesn't have a parallel port, however, you can still connect a parallel printer to the system. A USB-to-parallel-port adaptor allows you to hook up a parallel-port printer to a USB port on your computer.
