12/06/2022, 8:33 PMWhen you call the cfhtmltopdf tag in ColdFusion, it makes an API request to a Jetty-powered Java API which runs as the external PDF service which in turn runs the actual htmltopdf engine

There's also a portable QTWeb browser that uses the same HTML renderer. If it doesn't look good & print as expected with it, it probably won't work with WKHTMLTOPDF either.

I noticed that Google Maps is blocking it based on feature detection. (Its rare, but NodeJS w/Puppeteer works to convert pages/divs of very advanced HTML to PNGs for inclusion within a PDF.)

12/08/2022, 5:18 PMin reality i am looking for a PDF technology, not necessarily CF based, that has the most support for html, css, js (if possible)…so I will look at Puppeteer

12/08/2022, 6:24 PMI would definitely start with things like flex though, to begin narrowing down. https://azettl.github.io/html2pdf/CSS-Properties/F/#-flex
