Looking for PDF (and raster) printer drivers for XP

I'm working with running XP on a virtual machine, but forgot how it doesn't come with a PDF virtual printer driver.

Anyone know of any offhand? Google is coming up with some odd results. Essentially, I'd like to generate some PDFs out of printer output, in the most painless way possible. A PDF generating printer driver would be ideal.

Also I'm interested in a raster printer driver, too - but that is secondary to the PDF driver.

Thanks.
