On printer side it is available a different connector, named Centronics, according with the name of the first producer. On computer the port is a Female connector commonly named DB25 complete of 25 pins. The LPT allows the connection of many different peripheral devices and it transfers 8 parallel bits with the TTL standard.

Today the parallel port in the PC environment is almost no more used, but this doesn t happen in the industrial fields. The port came out as Unidirectional interface, and it sent data only from computer to connected peripheral, but then it has been improved with a Bidirectional standard (IEEE 1284). After time, when the bidirectional version was developed, it is widely used also to connect other peripheral devices as Scanner, ZIP unit, Hard Disk, CD-ROM reader, Webcam, etc. CENTRONICS interface and Parallel Printer Port LPT The Parallel Port, well known as LPT from Line Printer (that is a term derived from Line Printer Terminal) is an interface originally used to connect a computer to a printer or a plotter.
