Hardware printer ports
There are three primary types of hardware printer ports:
- Parallel port - A 25-pin connector, used with IEEE-1284 printer cables, that has a Centronics port on the end that connects to the printer.
- SCSI port - A less common type of connector, used with cables and printers that were SCSI compatible.
- USB port - Newest connector, used by most printers today.
Software printer ports
With a parallel printer, there are also software ports. These ports include LPT1, LPT2, LPT3, and LPT4. See our LPT definition for further information about this type of port.
