Standard, ECP, and EPP features. It has the following options:
[Disabled]
[3BC/IRQ7]
Line Printer port 0
[278/IRQ5]
Line Printer port 2
[378/IRQ7]

Parallel Port Mode
SPP : Standard Parallel Port
EPP : Enhanced Parallel Port
ECP : Extended Capability Port
ECP + EPP: Extended Capability Port + Enhanced Parallel Port
Normal
SPP/EPP/ECP/ECP+EPP
To operate the onboard parallel port as Standard Parallel Port only, choose
[SPP]. To operate the onboard parallel port in the EPP mode simultaneously,
choose [EPP]. By choosing [ECP], the onboard parallel port will operate in
ECP mode only. Choosing [ECP + EPP] will allow the onboard parallel port to
support both the ECP and EPP modes simultaneously. Choose [Normal] to
use Standard Parallel Port + Bi-Directional Mode simultaneously.
