Parallel Port Mode Enables you to set data transfer protocol for your
parallel port.
There are four options: SPP (Standard Parallel Port),
EPP(Enhanced Parallel Port), ECP(Extended
Capabilities Port) and ECP+EPP.
SPP allows data output only. Extended Capabilities
Port (ECP) and Enhanced Parallel Port (EPP) are bi-
directional modes, allowing both data input and
output. ECP and EPP modes are only supported
with EPP and ECP aware peripherals.
