This may be yesterday’s news, but if you are looking for a reliable (and free) PDF converter, may I suggest PrimoPDF?  I have been using it for months to convert my Word documents to PDF and it is great. 

Here’s a bit more:

PrimoPDF is a free tool for high-quality PDF creation, comprising a user-friendly interface that enables printing to PDF from virtually any Windows application.

• Completely free, not just a trial version, and no user registration is required.
• Ability to optimize PDF output for screen (online viewing), print (standard laser printers), ebook, and prepress.
• Resultant PDF output conforms to the PDF 1.4 specification.
• Secure PDF files with 40- or 128-bit encryption.
• Add document information (e.g. title, author, subject, keywords) to converted PDF files.
• NEW: Full support for 64-bit machines.
• NEW: Double byte character support.
• NEW: Support of non-TrueType fonts.
• NEW: Enhanced support for Microsoft Windows 98, ME, XP and Vista as well as improved PDF viewing support on non-Windows platforms.
• NEW: Ability to merge/append PDF files upon conversion.

That’s it.  I like the product and wanted to share…

(By the way, they also have a Developer API which I haven’t played around with yet.)
