Printing documentation broken

[youradds]

The printing of documentation pages (http://v4-alpha.getbootstrap.com/layout/grid/ for example) is broken. I tried printing it on paper, and it cuts the page off. I then tried it with a PDF printing, and same issue (see attached). It seems to negative margin the pages, so they get cut right down the middle, so are unusable.

As there are also issues in IE11 relating to printing, closing this issue in favor of #21092
