Small advertisement: Vivliostyle, whom I'm working with/for, is open source
and does printing via browser technology. It is not quite perfect yet, but
at quite an advanced stage and hopefully it should be able to do a lot of
what Prince/AntennaHouse can do with HTML in the near future.

Right. Well, actually the issues with the print-to-pdf features Leonard
mentions were things we were considering when I was working on another open
source predecessor to Vivliostyle.js with another group. Our conclusion
back then (in 2012) was that people were still using PDFs for onscreen
reading. But as far as we understood, the main reason for that was that
certain things found in scientific texts (mathematical formulas, footnotes,
etc.) were just not very easily displayable using epubs.

We were considering whether we could add such features to browser-created
PDFs. One possible solution we came up with would be to take the PDF as it
comes out of the browser and enhance it. To do that one would however have
to give complex instructions to users ("After you create your PDF, please
go to site X and upload it then, then download another PDF form there and
use that") or give them an augmented version of the browser, both of which
are not easily done. We ended up just not doing them.
