title: How can one detect via Javascript if a print stylesheet is in effect?
body: <p>I would like to have alternate behavior during a print stylesheet on a web page.  Something along the lines of:</p>
  
  <blockquote>
    <p>If this page is being printed, don't
    bother calling SWFObject to summon an
    .swf into existence.  Just leave the
    HTML that the Flash will replace.</p>
  </blockquote>
  
  <p>I've tried things like setting a known element to a known style that exists for the screen but not for the print stylesheet.  But getting a "style" via Javascript doesn't get a <em>computed</em> style.</p>
  
  <p>Summary: In a cross-browser way, is it possible to tell which stylesheet is in effect?</p>
