Pat,
If your printer port has died, start by removeing the port from device manager.
(right click on my computer and select properties,)
Expand the ports branch.
Select the printer port and click remove.
Close the dialog boxes, and shut down.
When you re-boot, go into BIOS settings, and disable the on-board printer port.
Now, you can use LPT1 for your add-in card printer port.
Some cards use jumpers, others use software.
As far as your printer driver, there should be a configuration page under printer properties where you select the port the printer is connected to.
