ECP
The parallel port operates in the extended capabilities
port (ECP) mode. The ECP mode supports
bi-directional communication between the system and
the parallel port device and the transmission rates
between the two are much faster than the SPP mode.
ECP+EPP
The parallel port is compatible with both ECP and EPP
devices.
