When I've seen this it has been browser specific, though I can't remember which way around (in fact it might be sometimes one that does and sometimes the same one that doesn't...) so if you get odd printing results with Chrome try in FF (or vice versa, or add Edge into the mix if on Windows, or ...).
Yes, CSS3 has a new module CSS Paged Media Module [0]. This should eventually replace XSL-FO for formatting for print. What I don't understand is who finds these useful anymore? except big enterprises like telecoms with dying legacy requirements. Those requirements will get totally replaced by web... Maybe there is still a niche for archiving with PDF/A
*Maybe publishers that don't want to be locked in with a single formatting tool (indesign)
Yep. Before that we used to wrap things in table cells to simulate page-break-avoid. This mostly worked. "Orphan" control was impossible at the time. I think most of the browsers do an ok job. Price ml does it all. Including things like toc generation and forcing sections to start on the front of a piece of paper or have a gutter in the "inside" of the page.
