Answer : Problem: what 's the difference between  ECP and EPP

Check out www.whatis.com for an excellent on-line glossary. Here's an excerpt related to your question:

EPP/ECP (Enhanced Parallel Port/Enhanced Capability Port) is a standard signaling method for bi-directional parallel communication between a computer and peripheral devices that offers the potential for much higher rates of data transfer than the original parallel signaling methods. EPP is for non-printer peripherals. ECP is for printers and scanners. EPP/ECP are part of IEEE Standard 1284, which also specifies support for current signaling methods (including Centronics, the de facto standard for printer communication) so that both old and new peripherals can be accommodated.
