I had purchased a new Dell system with Parallel Port. I had found the details of all addon card in the slim pc that I have. The card is like a plug and play device and there is no need of driver I think. After connection when I started the system I found that the card is grayed out and does not respond at all. I had connected a separate machine to the system but somehow it fail to work. I hope there will be some kind of way by which I can fix this thing.
