Scanning negatives from film to print a normal picture? Are there any printer models that can do this because I have never heard of that before. I would think if you scan a film negative all you will get is a dark or blank output, not a full blown picture like you were if you broght the negatives to a photo developer.
You might have some luck with a custom technique like this:
