Enhanced Parallel Port
The Centronics parallel port only allows data to be sent from the host to a peripheral. To overcome this the IEEE published the 1284 standard which is entitled ‘Standard Signaling Method for a Bi-directional Parallel Peripheral Interface for Personal Computers’. It allows for bi-directional communication and high communication speeds, while it is backwardly compatible with existing parallel ports.
