Enhanced Parallel Port (EPP) specification. EPP uses the existing
parallel port signals to provide asymmetric bidirectional data
transfer driven by the host device.
ECP
The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses the DMA
protocol to achieve data transfer rates up to 2.5 Megabits per
second. ECP provides symmetric bidirectional communication.
Bi-Dir
Data can be sent to and received from the parallel port.
