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.
