Testing print styles

[jamescryer]

You could do this before taking a screenshot. (Assumes jQuery is on the page)

casper.evaluate(function(){
  $('link:not(link[media*=print])').remove()
  $('link[media*=print]').attr('media', 'all');
});

I don't know if there is anything native to PhantomJS you could use, but the above script would essentially do the same, perhaps combine with setting viewport
