When printing this file http://www.iro.umontreal.ca/~bengioy/dlbook/ml.html (whether downloaded or from the web) only the first page gets printed.
There're no error messages also with --debug option on.

Please advise.

If the entire book is inside an absolutely positioned block then it will not be split across multiple pages.

Well, then it looks as a bug, since e.g., Chrome is perfectly happy to print all pages.

This looks like a LaTex document that was converted to PDF, then converted to HTML with pdf2htmlEX, resulting in some of the more horrible HTML and CSS I've seen.

Removing the absolutely positioned container does result in multiple pages in Prince, but there would be more style work required.

I did find a discussion on taking this HTML and converting back to PDF: https://github.com/coolwanglu/pdf2htmlEX/issues/576

Good luck.
