![]() ![]() With each byte sent out, it sends a handshaking signal so the printer can latch the byte.įirst introduced in 1970, parallel ports were originally designed to connect business computers to printers. When using a parallel port, the computer sends the data 1 byte at a time (8 bits in parallel, as opposed to 8 bits serially as in a serial port). Secondly, what type of connectors are available in a parallel printer cable? The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers.Ĩ data, 4 output control, 5 input control, 8 groundĭB-25, DB25F, "Centronics" 36-pin Amphenol, DC-37, othersĬonsidering this, how does a parallel port work? ![]() In the past, the parallel port was widely used for printers and occasionally for connecting other devices externally, but was superseded by USB. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight data bits transferring simultaneously). It is often called a Centronics interface after the company that designed the original standard for parallel communication between a computer and printer.Īlso to know is, what is a parallel port used for? ![]() On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth.
