<body>
  An example dynamic page that is converted to PDF on 8x14 paper, 
  in landscape mode, with 1.0cm margins!<br /> 
  And what about <sub>subscript</sub> or <sup>superscript</sup>?<br />
  Hmmm...one last test, special characters: &alpha; &copy; &#187;<br /><br />
  This document has been encrypted with the helper PDFEncryptor class so you will need to
  enter "foobar" for the password<br />
  This should open straight into your PDF reader, 
  but, if not, click <a href="<?php echo $linkToPDF; ?>">here</a> to view the PDF file.<br />
  <div class="noprint">This should not show up.</div>
