I recently found a new solution that is open source that is free for private or commercial use. The program is called PDFCreator, and its featured packed. Below is a brief list of some of the key features:
- Create PDFs from any program that is able to print.
- Encrypt PDFs and protect them from being opened, printed etc.
- Send generated files via e-mail.
- Create more than just PDFs, you can also make: PNG, JPG, TIFF, BMP, PCX, PS, EPS
- Merge multiple files into one PDF
