title: Firefox prints second page blank
body: <p>Hello I've a HTML page and I want to print it on 2 pages, but when I print it in Firefox the first page is ok and the second is blank.
  I've try to print the page with different printers and PDF, I've always the same problem.
  I've try Firefox for macOsx an it has the same problem.
  In other browsers (IExplorer and Safari) works fine.</p>
  
  <p>this is the code:</p>
  
  <pre><code>        &lt;div id="corpo_centrale"&gt; 
          &lt;div id="contenitore_misure_stampa"&gt;
              &lt;div id="sfondo_misure_stampa"&gt;
              &lt;img src="images/stampa-risultati-1.jpg" width="1026"/&gt;
              &lt;/div&gt;
              &lt;div id="misure_stampa"&gt;
              some text
              &lt;/div&gt;
          &lt;/div&gt;
          &lt;div style="page-break-after:always"&gt;&lt;/div&gt;
          &lt;div id="contenitore_risultato_stampa"&gt;
              &lt;div id="sfondo_risultato_stampa"&gt;
              &lt;img src="images/stampa-risultati-2.jpg" width="1026" /&gt;
              &lt;/div&gt;
              &lt;div id="risultato_stampa"&gt;
              some text
              &lt;/div&gt;
         &lt;/div&gt;
    &lt;/div&gt;
