Option for page breaks while printing

[bamhm182]

What is Happening

When printing, multiple chapters can print on one page. This makes it a little difficult to find the beginning of new chapters as in some cases, the chapter may start at the bottom of a page.

What is Expected

As in real printed books, when a book is printed, the start of a new chapter means the start of a new page.

Proposed Resolution

The code <p style="page-break-before: always"/> can be added to the end of every chapter while on the print.html page in order to allow for the next chapter to be printed on a new page.

I realize this may not be ideal for all cases, so I also propose an option like [page-break-between-chapters] = true be available in the book.toml

As a temporary workaround I've added:

h1 {
    page-break-before: always;
}

to print.css.

Is there a way to revert this? For a "book" with small chapters it's better to print on the same page.

I looked at the theme files, but the only mention of page-break-before is in highlight.js.

Sure, I think that can be added. I'm a bit surprised that is something that would be desired, but if you'd like, you can post a PR that reverts 0eb23ef to add the option back in.

My use case is using mdbook as lazy way to have a personal webpage and a CV in one 🙂

@ehuss I posted a PR to revert the change, #1728. Can you please have a look?

Closing as I believe this is resolved by #1728.

Just curious: It feels to me as if CSS is the right place to specify things like line breaks, no?
