PrimoPDF 4 converts just about any file type to a PDF, using the source program the file was created with and its print command. Two new changes make the program easier to use and more useful. The interface redesign is definitely easier to navigate, and users can now choose to email the PDF instantly after its creation.
The conversion process from whatever document is on your screen to PDF is quick and efficient. Other features include a security feature, which allows the user to wrap the PDF in 40-bit or 128-bit encryption, PDF merging, and password protection. The user also can restrict editing of the new PDF, leaving comments and making other changes.
Primo'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.
