- An IEEE standard for high-speed bi-directional parallel ports. It provides for multiple devices including printers, scanners, and external drives to be connected to a parallel port, allows for an extended cable, has multiple modes including ECP and nibble, and is backwards compatible with other standards, such as that of the Centronics parallel interface. Also called IEEE 1284 standard.
