So, I was checking out different free (or open source) pdf creating software for windows. Several different ones are out there I eval'd:

CutePDF_Writer
PDF_Redirect_v225
PDF995
PDFCreator
PrimoPDF

First off, let me say that PrimoPDF was a flop. It wanted me to download .NET 2.0, which was over 20 Megs on top of the 20 megs for the software itself, and seemed more bloatware than anything else. I moved on.

PDF_Redirect v2.2.5 seemed to be the most complete and full featured of the free software. It didn't look very professional though, and seemed to have been shareware. All in all, though, pretty decent package.

PDF995 was a standard printer based package. No bells and whistles, but just got the job done. It had a nag screen though... which was kind of annoying.

CutePDF Writer again was OK. Nothing special just a normal PDF printer, etc etc. It did require (though) ghostscript install (8mb easily downloadable from their website). They needed to distribute it separately, presumably, because of the GPL license on ghostscript. It had a nag message on the "Save as..." dialog box.

PDFCreator is by far the best. It was easy to install, looked very professional interface. Has a sourceforge account (I didn't check the license, but it was some form of open source). It installs itself in the menu/toolbar of IE for one click printing. Pretty slick; definitely the winner in my book.

I found that http://www.gtlib.gatech.edu seems to be a pretty good (and fast) server for the cygwin downloads.
