Centronics ConnectorsCentronics connectors are a type of D-shaped electrical connector commonly used for parallel communication. They are named after the Centronics company, which developed the original version of the connector in the 1970s. Centronics connectors are typically used to connect a computer to a printer, but they can also be used for other types of parallel communication. The connectors have a row of pins on one side and a corresponding row of sockets on the other side, allowing them to mate with each other. They are generally easy to use and have become a standard in the computer industry for parallel communication.
