Hrqls: I've taken free (most likely wrongly) to mean free in the terms of the FSF (Free Software Foundation) and in monetary terms, and a quick google turns up PDFcreator.

A screenshot (if you care) is here:
http://sourceforge.net/project/screenshots.php?group_id=57796

You can download it: http://sourceforge.net/project/showfiles.php?group_id=57796

You proboably want Patch02-PDFCreator-0_8_0.exe

Free as in speech and beer!
