Recommendations for PDF Creation Libraries?

Hi everyone,

I want to give users the option in my Web app to convert Web site content to a PDF to print or download.

I'm looking for recommendations for a PDF library which works well with ci, doesn't hog too much space and which has at least a decent chance of being supported for a while!

I tried MPDF and after an hour couldn't get it to work. I think some of the tutorials are out of date. If that is in fact the best one I'll spend another hour or two trying to make it work, but I'm thinking maybe there's a better option?

Thank you!
