我使用dompdf将html转换为Pdf，我想打印它。我的问题是如何在打印窗口中打开pdf文件而不是打开下载对话框？

include('dompdf/dompdf_config.inc.php');

$savein = 'pdfdirectory/';  

$html = " my htmlcode here " 

$dompdf = new DOMPDF();
$dompdf->load_html($html);            
$dompdf->render();      

$pdf = $dompdf->output();             
file_put_contents(($savein.'file.pdf'), $pdf);           

$dompdf->stream('file.pdf');
