EPP
Short for Enhanced Parallel Port, EPP is a parallel port mode that is capable of working about twice as fast as the original parallel ports, and can transfer data back and forth between a peripheral and a computer at the same time.
This parallel port mode was first developed in 1991 by Intel, Xircom and Zenith, at the same type the extended capabilities port (ECP) was being developed by Microsoft and Hewlett-Packard. EPP is a popular 8-bit port for many portable computers and operates close to ISA bus speed and can achieve transfer rates up to 1 to 2MB/sec of data.
EPP version 1.7 was released in 1992 and later adapted into the IEEE 1284 standard. All additional features are adapted into the IEEE standard.
EPP version 1.9 never existed.
