An IEEE 1284 36-pin male micro ribbon printer cable connection. The computer side normally uses a DB-25 port instead of this connector. IEEE 1284, also known as the Centronics port, is a standard that defines bi-directional parallel communications between computers and other devices.
Printer cable refers to the cable that carries data between a computer and a printer. There are many different types of cables, for example: Serial: RS-232, EIA-422; Parallel; FireWire; USB; Parallel port printers have been slowly phased out, and are now difficult to find for the most part, being considered as an obsolete legacy port on most ...
Today, the parallel port interface is virtually non-existent in new computers because of the rise of Universal Serial Bus (USB) devices, along with network printing using Ethernet and Wi-Fi connected printers. The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers.
This so-called LapLink cable or null-parallel cable is capable of faster transfer rates than the traditional null modem serial cable. At the time, almost all PCs had a parallel printer port, but neither USB nor modern Ethernet was available. A Laplink cable can be seen as a parallel equivalent to a serial null modem cable. Because of the higher ...
Blue or magenta: Parallel printer DB-25; Amber: Serial DB-25 or DB-9; Pastel pink: Microphone 1/8" stereo (TRS) minijack; Pastel green: Speaker 1/8" stereo (TRS) minijack; Additionally, USB ports are color-coded according to the specification and data transfer speed, e.g. USB 1.x and 2.x ports are usually white or black, and USB 3.0 ones are blue.
The decreasing cost and better performance of integrated circuits has led to serial links being used in favor of parallel links; for example, IEEE 1284 printer ports vs. USB, Parallel ATA vs. Serial ATA, and FireWire or Thunderbolt are now the most common connectors for transferring data from audiovisual (AV) devices such as digital cameras or ...
