CutePDF Writer: Create professional quality PDF files

CutePDF Writer is a free, comprehensive application for creating high-quality PDF files from almost all known printable documents.
CutePDF Writer installs as a “printer subsystem” so basically you’ll be able to create PDF documents from any Windows application that has printing options.

To do that, open the File>Print menu from within the application and choose CutePDF Writer from the list of available printers. After that, all you have to do is to select the output directory and the filename for your new PDF document.
