I looked at some FM code that combined pdf files, but it was very slow. My solution is that I open the attached pdf files apart, each one, and then the user can print them. - Not too neat, but it works. - No problems with the jpg files and I guess there won't be with gif files either. BUT. What is a smart thing to do with Word and Excel documents? (It seems impossible to append them to the (existing) pdf invoice file, or at least I haven't been successful in doing it.)
