<html>
       <head></head>

session_start();
error_reporting(-1);    
//include files and mpdf library

$id=(int)$_GET['id'];
//some mysql query and and

$html = "<div id=\"print_target_box\" style=\"display:block;\">";
// some php mysql manipulations

// many div and block concatenate by  $html.="";

$html .="</div>";  
$mpdf = new mPDF(); 
$mpdf->debug = true;

one image `go.gif was missing on server and this does not displaying error bcoz error_reporting was set to 0 in below included php page..

If you edit file mpdf.php and find the line with that error message in it:

if (!$im) { return $this->_imageError($file, $firsttime, 
    'Error parsing image file - image type not recognised,
      and not supported by GD imagecreate'); }

change this to:
