Do you still have the printer port installed? If yes or no, if there are any LPT ports listed in device manager, delete them then restart the computer.

Part of the problem may be a mis match between the configuration of the card and what the computer thinks is there.

by removing the devices installed software it may re-find the card and configure it properly.

Ideally you'll remove the card, remove any installed drivers, then restart the computer without the card installed. check for resources available for IO and IRQ. once you know what's available it's easy to configure the card to use the available resources. that is, on the big guess that the card is user configurable.
