G-2 Glossary
ECP
Extended Capability Port. ECP is a protocol that provides for a high
performance bi-directional communication path between the host
adapter and the peripheral. To take advantage of ECP mode, the parallel
port must be capable of operating in ECP mode, there must be a port
driver that knows how to operate in ECP mode, and the printer or
peripheral must be designed to operate in ECP mode.
EPP
Enhanced Parallel Port. EPP is a protocol that provides for a high
performance parallel port link that is still compatible with the standard
parallel port. Details of this standard protocol are available from the
IEEE 1284 committee.
