Three letter acronyms and initialisms can mean a great many different things, depending on the context in which they are used.
among other things, EPP can mean:
Similarly, ECP can mean:
Unidirectional mode or bidirectional mode. If using more modern standard ieee-1284, EPP or ECP Also, ECP & EPP
ECP is faster (because it uses a DMA channel).
bi-directional parallel communications
ECP was designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
ECP and EPP
An occasion when you need to disable the ECP mode for parallel port is when resource conflicts occur. In such a case, the EPP mode is the better option.
Standard parallel port (SPP), Enhanced parallel port (EPP), and Extended Capabilities port (ECP)
Standard parallel port (SPP), Enhanced parallel port (EPP), and Extended Capabilities port (ECP)
Extended Capabilities Port (ECP) as designed to increase speed over EPP by using a DMA channel; therefore, when using ECP mode, you are using a DMA channel.
# If you are having problems with resource conflicts, you could try disabling ECP mode for the parallel port. EPP mode gives good results and does not tie up a DMA channel.
ECP is short for emergency contraceptive pill
