I have some PDF Maker by - from freeware and paid versions. The problems I had again and again: Either the software constantly put out, ie each reinstall, or the conversion was in the representation of their own way, that is the letter l was always displayed in bold; Fonts were changed, etc.
With Acrobat Pro 11 no more problems, accurate conversion and display as the original plus a lot of other functions. Admittedly, the program is not cheap, but just in a business context a must for me.
