Thanks for the suggestion.  However, I already had my parallel port set
to EPP in the BIOS of the host machine.

The solution for the S2885 was adding two three pin jumpers at J94 & J95
as suggested earlier by one of Tyan's engineer via YhLu.  Plus
connecting pins 2 & 3 of jumper J94 and connecting pins 1 & 2 of jumper
J95.  Pin 1 is the closest one to the board's nearest edge.

Thank you everyone for responding to my question.
