The Centronics parallel interface quickly became a de facto industry standard manufacturers of the time tended to use various connectors on the system side, so a variety of cables were required. The now-familiar connector was selected because Wang had a surplus stock of 20,000 Amphenol 36-pin micro ribbon connectors that were originally used for one of their early calculators. An Wang, Robert Howard and Prentice Robinson at Wang Laboratories. |title=Print Unchained: Fifty Years of Digital Printing: A Saga of Invention and Enterprise |publisher=DRA of Vermont |location=West Dover, VT |year=2000 |isbn=0-970] The interface was developed by Dr. The Centronics Model 101 printer was introduced in 1970 and included the first parallel interface for printers. The IEEE 1284 standard defines the bi-directional version of the port. It is also known as a printer port or Centronics port. A parallel port is a type of interface found on computers ( personal and otherwise) for connecting various peripherals.
