I've never used win2pdf, but I can vouch for a free, open-source PDF program called PDFCreator. Get it here:
http://sourceforge.net/projects/pdfcreator/
It installs itself as a printer, so when you want to create a PDF file from a document, you just use PDFCreator as your printer and it saves the result as a PDF file. You can then open it and do whatever you like and print it to your printer. I actually use PDFCreator a lot just to save things like receipts for online purchases, rather than printing them on paper.
