title: background printing issue with twitter bootstrap
body: <p>I'm using Twitter Bootstrap and try to print page with background.
  I tried all the options in the web browser , but it doesn't work.
  If I don't include twitter bootstrap, the printing of the background works perfectly.
  (by the way, on this particular page I'm not using anything related to TBS).</p>
  
  <p>Is there anything I can do to make it work (a kind of reset ) without excluding TBS ?</p>
