I am also a big fan of Print to PDF. I've actually built a simple bookmarking service [0] that does just this.
EmailThis extracts meaningful content from web pages and sends it to your email inbox. You can also tell it to save a PDF copy of each page, in which case the PDF is sent as an attachment.
Print-to-Pdf is done using Headless Chrome (so it works exactly like doing a Ctrl-P).
I find that the Print to PDF works best because it gives you a copy of the web page even if the original one disappears. Also, none of the content extraction services (mine included) work in 100% of the cases. Sometimes, they might incorrectly remove images and other meaningful content. So in such cases, having a full PDF snapshot is quite handy.
Let me know what you guys think.
