There are many types of parallel ports, but the term has become most closely associated with the printer port or Centronics port found on most personal computers from the 1970s through the 2000s. It was an industry de facto standard for many years, and was finally standardized as IEEE 1284 in the late 1990s, which defined the Enhanced Parallel ...
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 ...
Computer ports in common use cover a wide variety of shapes such as round (PS/2, etc.), rectangular (FireWire, etc.), square (Telephone plug), trapezoidal (D-Sub — the old printer port was a DB-25), etc. There is some standardization to physical properties and function.
For example, on the original IBM PC, a male D-sub was an RS-232-C DTE port (with a non-standard current loop interface on reserved pins), but the female D-sub connector on the same PC model was used for the parallel "Centronics" printer port. Some personal computers put non-standard voltages or signals on some pins of their serial ports.
Any Amiga printer driver had to communicate though the standard Amiga printer.device (the default standard hardware device of Amiga dealing with printers), and the standard parallel.device (which controlled parallel port) and the driver would then control the printer on its own. Amiga printer drivers were an innovation for their time.
a Print Dialog box, which allows printer properties to be modified; a Print Manager, which allows management of printers, such as adding and removing printers, through an Add Printer Wizard; a Job Viewer/Manager, which manages printer jobs, such as hold/release, cancel and move to another printer; a CUPS configuration module (integrated into KDE)
A male D-subminiature connector used for an RS-232 serial port on an IBM PC compatible computer along with the serial port symbol. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]
