I'm in the Army and we still manage property using archaic paper based forms from the 1980s. Fortunately these forms have transitioned over to PDFs and can use digital signatures (which is another key feature of the PDF that we need). I am unfamiliar with Crystal Reports but even if I did familiarize myself with it, I'd have a long road of trying to get it authorized for use on our networks. MS Office and Acrobat is already in our baseline image.
The video below is version 1 of the project I'm updating now. This will be version 3 and PDF filling will be part of it.
