Shoot, I was just planning to use this for generating PDFs out of a URL on nodejs. Does anyone know of any other library / module out there that is good at this?
Sadly you get 0 control over headers and footers of the output PDF, meaning you get lovely crappy page numbers around the place with no way to turn them off. This is why, sadly, I have to keep my command line markdown -> pdf converter (https://www.npmjs.com/package/mdpdf) using Phantomjs.
So this does work for very basic pdf printouts, but so far phantom is the only tool that offers full control over the PDF output. Even down to things like margins, paper size, etc.
