HTML2PDF

Bonjour,

J ai suivi le tuto HTML2PDF classique et cq fonctionne parfaitement. J ai essaye de l integrer a cakephp en suivant ce sujet :
http://www.grafikart.fr/forum/topic/2081

Mais il m affiche :

%PDF-1.7 3 0 obj <> /Resources 2 0 R /Contents 4 0 R>> endobj 4 0 obj <> stream x??X?n?0??S??m?'?c?W??nR/?2E???@lo?G?k???g?1)??D????}??9@ ?0n??7xxT???|$?R?9?#h~@@?0D]???? ??U??e???{?n?9?!

Et ne genere donc pas le PDF.

Mon controller :

public function admin_generate($id) {

    }

Ma vue admin_generate :

<?php 
App::import("Lib", "html2pdf/html2pdf");
ob_start(); ?>
<style type="text/css">
    table{ width: 100%; font-family: helvetica; font-size: 14px;}
</style>
<page backtop="10mm" backbottom="10mm" backleft="10mm" backright="10mm" footer="page; date;">
    <page_footer><hr /></page_footer>
    <table>
        <tr>
            <td style="font-weight:bold;">TEST</td>
        </tr>
    </table>
</page>
<?php $content = ob_get_clean(); 
try {
    //On declare un nouvel objet
    $pdf = new HTML2PDF('P','A4','fr');
    $pdf->pdf->SetDisplayMode('fullpage');
    $pdf->writeHTML($content);
    $pdf->Output('test.pdf');
    //$pdf->Output('test.pdf','D');//Force le telechargement du PDF
} catch (HTML2PDF_exception $e) {
    die($e);
}
?>

Ca peut venir de ou ?

Merci d avance.
