title: hide HTML div when printing page
body: <p>I have a XHTML-based page which contains admin information. The admin should be able to print the page, but I would like it to hide their information.</p>
  
  <p>Is there a way to set a print area when printing a page, or is the only viable solution to open up a secondary page without the admin information when clicking on the "print" button?</p>
  
  <p>Thank you!</p>
