Definition

LPT is Commonly known as the parallel port and typically used as the printer connection device. For distances limited to 20 feet or less. Faster than serial COM ports but more expensive. A typical LPT port reaches a speed of 150kb/sec. There can be more than one LPT ports in a computer and to differentiate them they are labeled with a number after LPT. It is most common to have only one for the printer called LPT1. It is shaped as a trapezoid with the short end in the bottom and 2 rows of pins, one 13 and other with 12 pins.
