I want to generate PDF in my custom module. Using print module we can print node. But I have made html in my custom module and that I wanted to make pdf and save it in files.

I have tried custom **dompfg** library but its working. 
i wanted to do something like this:

```
$html = "<h1>Header</h1><P>Pdf generated.</p>";

include ("mpdf.php"); /// This will be something to include for mpdf 
$mpdf=new mPDF('win-1252','A4','','',20,15,48,25,10,10); 
$mpdf->WriteHTML($html);
$mpdf->Output('../default/files/users/filename.pdf','F'); 
exit;

```

Any suggestions?
