Personally, I don’t use PDFs for printing, but like PDF word documents, you can insure that can’t be (easily) modified, so that you have control over the final result. I’ve heard a couple of photographers in the photojournalist field mention that... As was mentioned, many aps like PS, PSE and LR allow saving as a PDF, but I don’t know if it degrades the resolution. I’m betting Burkphoto knows the answer to this.
I often make proofsheets from portrait shoots and save them as PDFs to e-mail them to clients. They don't appear to lose any resolution.
