Full width printability, an idea...

[DenverDias]

For bootstrap implemented pages with sidebars, where the sidebar should be prevented from being printable using "hidden-print" sure hides all of the sidebar stuff.

Chrome seems to be able to handle it pretty well by printing as if the page were under 768 wide (for bootstrap, in the "sm" range) thus making sure that a right sidebar with a "hidden print col-md-*" set of classes would properly disappear in the print output. However, Safari (and maybe some other browsers, I've not tested it on the other) doesn't play well; printing such a page will leave a massive blank area where the sidebar was supposed to be. Reducing the width of the window would remedy the problem but that would have to be done by the user. It would be nice if bootstrap had a separate class (perhaps "print-fullwidth") that could be assigned to the div of the content intended to be printable, so that the content prints at full width unambiguously in all browsers without additional intervention from the user.

Last time we checked (in #12078), Chrome uses the XS grid when printing on US Letter paper.

I don't think we'll be adding anything more to our print styles, in v3 or v4. Starts to get too specific honestly.
