I once was forced to make prints from slides. I had a slide film in my camera (because I was supposed to take some pictures on slides for university), but all my aviation collection is prints. So I came to the airport and found this one:

I took slides of it and later made prints from these slides to put them into my collection.
You can order prints from slides in normal photo labs. It doesn't cost that much more. The quality is OK (please note: I'm not saying amazing
). It was OK for my collection, but I doubt it would make it on airliners.net. But that does not necessarily have to be the fault of the slide-to-print action. It could also be that I chose a rather cheap slide film, that the weather was not the best or that I was surprised by the plane taking off on the shortest runway available and I couldn't get in a good position.
So the answer is: Yes, you can make prints from slides, and they have a fairly good quality.
