Yes, I know it’s Christmas… but there’s one great app for Windows that hasn’t been updated in awhile. And, as a Christmas gift, it has been updated once again. PDFCreator creates a virtual printer that generates a PDF. No Adobe Anything required.
I haven’t taken a look yet at the change list for 0.9.5, and I’m not sure if Vista support was added (there was a bounty out there for it). Sound off in the comments with your experiences and let everyone know if it does indeed work in Vista now.
