Looks very promising. Open to suggestions if others have better PDF-generating solutions!
Also, the correct link is http://phantomjs.org/
(There's also a free version for non-commercial users, but it's really only usable for evaluation, because it adds a PrinceXML logo to the generated PDFs.)
Maybe the prior HTML rendering functions are still in the source. I think it's worth downloading and checking.
You could look into something like http://prawn.majesticseacreature.com/ though.
Also, it is surprisingly fast.
Concerning quality of the PDF document, LaTeX very good in relation to other creators.
For being a universal document format, it's very frustrating that PDF readers don't make using them easier.
Prawn seems to have come a long way since I used it last - and has addressed all the limitations that pushed me towards LaTeX in the first place.
Definitely worth looking at Prawn again in my opinion.
I've used wkhtmltopdf, but lately I've discovered that Chrome does a pretty good job if you print a page, then specify print-to-file to a PDF destination.
How have you found it?
