title: change top margin of second page using mPDF
body: <p>I'm dynamically generating PDFs with an unknown page count. mPDF is working good, but the top margin on the second page is gone. How can I set the margins for all pages with the document?</p>
  
  <p>I've tried the following, but it has no effect:</p>
  
  <pre><code>$mpdf = new mPDF('', '', 0, '', 15, 15, 15, 15, 8, 8);
  </code></pre>
