title: show div only when printing
body: <p>Let's say that I have </p>
  
  <pre><code>&lt;div id="printOnly"&gt;
       &lt;b&gt;Title&lt;/b&gt;
       &lt;p&gt;
          Printing content 
       &lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is it possible to hide this div when page rendering and to show only when printing this div?</p>
