A parallel port is an output device that allows a computer to transmit data to another device using parallel data transmission—several bits sent simultaneously over separate wires. PC parallel ports are usually designated as LPT1, LPT2, and so on. This is in contrast to a serial port, which transmits data sequentially, one bit at a time.
A parallel printer is a type of printer that connects to a computer using a parallel port, allowing for faster data transfer rates compared to serial connections.
