We have added a possibility to render the website as a page PDF, it is essentially the equivalent of the full-page screenshot, but as a PDF with one page only. Use the pdf_fit_one_page option to achieve that.
And you can force our PDF API (now we call it so) to render graphics, which is not enabled by default. Most of our current customers use PDF rendering without graphics. Use the pdf_print_background option to achieve that.
Happy to share the updates and more soon to come!
