In particular, as of Chrome v32 and regardless of margin settings, Chrome uses a viewport width significantly narrower than the physical paper size when resolving media queries while printing a webpage. This can result in Bootstrap's extra-small grid being unexpectedly activated when printing. [See #12078 for some details.](https://github.com/twbs/bootstrap/issues/12078) Suggested workarounds:
+* Embrace the extra-small grid and make sure your page looks acceptable under it.
+* Customize the value of the `$grid-breakpoints` Sass variable so that your printer paper is considered larger than extra-small.
+* Add custom media queries to change the grid size breakpoints for print media only.

Also, as of Safari v8.0, fixed-width <code>.container</code>s can cause Safari to use an unusually small font size when printing. See <a href="https://github.com/twbs/bootstrap/issues/14868">#14868</a> for more details. One potential workaround for this is adding the following CSS:
{% highlight css %}
