สอบถามผู้รู้เกี่ยวกับการใช้ mpdf ครับ ผมใช้ version 6.0 ครับ

require_once('../style/mpdf60/mpdf.php');
ob_start();

$html = ob_get_contents();        //เก็บค่า html ไว้ใน $html 
ob_end_clean();
$pdf = new mPDF('tha','A4','0','THSaraban');
//$pdf = new mPDF('tha', 'A4','0', 'THSaraban');   //การตั้งค่ากระดาษถ้าต้องการแนวตั้ง ก็ A4 เฉยๆครับ ถ้าต้องการแนวนอนเท่ากับ A4-L
$pdf->autoScriptToLang = true;
$pdf->autoLangToFont = true;
$pdf->SetDisplayMode('fullpage');
$pdf->WriteHTML($html, 2);
$pdf->Output();  

<style type="text/css">
