Printing broken in IE11 and Firefox

Using the v4 alpha documentation as a case in point, when printing in IE11 only the very first page is printed (instead of 17 or so pages, only 1 page is printed), while printing in Firefox results in all pages after the first one being offset to the left and cut off.
