Ask HN: How do you generate PDFs?

Given a complicated view mixed of HTML & various JavaScript widgets that range from SVG to canvas. How do companies make beautiful PDF reports?

Started with wkhtmltopdf, then started investigating the SASS industry like DocRaptor and the parent PrinceXML.

Started messing with headless Chrome to just take screenshots of the widgets and combine those images into a PDF, but its quite hacky.

What do people do in situations like this?
