PrimoPDF 3 converts just about any file type to a PDF, using the source program the file was created with and its print command. The interface could be nicer; it's uncluttered but also uninteresting. Previous versions required the user to go through the Save As menu. The reason why the publisher changed it to Print isn't obvious. Regardless, the conversion process is quick and efficient. Other changes include a security feature, which allows the user to wrap the PDF in 40-bit or 128-bit encryption, and password protection. The user also can restrict editing of the new PDF, leaving comments and making other changes.
The program's size is surprisingly large for such an unobtrusive app, and it's absolutely necessary to launch the read-me file at the end of installation, since the application loads no icons and leaves no other visible traces on your machine, except in the Start menu's All Programs.
