- parallel port
The connection on a computer to which you attach a printer. The connector on the
computer is a 25-pin D-shaped female connector. The cable
has a 25-pin D-shaped male connector on the computer end,
and a round, mouth-like Centronics connector for the printer end. A common dirty
trick of retailers is to leave out the printer cable, then charge $25 extra for it later. Make sure the cable is included when you
buy a computer or a printer. Most computers have only one port, called lpt1: Some have a second one labeled lpt2: and
a handful have even a third lpt3:. Printer cables should be
as short as possible. Every extra foot means extra headaches and flaky operation.
Never go beyond 10 feet unless you have special low capacitance cables. Since
Windows-95 does not use the IRQs (Interrupt Requests)
for its printer support, Windows-95 is fairly forgiving about configuring your
parallel ports improperly. However, the following is how they should be set up.
