รบกวนช่วยดู FPDF ให้หน่อยครับ เวลา run บน server แล้ว generate เข้า client ไม่ได้ ครับ

function Output($name='', $dest='')
{
	// Output PDF to some destination
	if($this->state<3)
		$this->Close();
	$dest = strtoupper($dest);
	if($dest=='')
	{
		if($name=='')
		{
			$name = 'doc.pdf';
			$dest = 'I';
		}
		else
			$dest = 'F';
	}
	switch($dest)
	{
		case 'I':
			// Send to standard output
			$this->_checkoutput();
			if(PHP_SAPI!='cli')
			{
				// We send to a browser
				header('Content-Type: application/pdf');
				header('Content-Disposition: inline; filename="'.$name.'"');
				header('Cache-Control: private, max-age=0, must-revalidate');
				header('Pragma: public');
			}
			echo $this->buffer;
			break;
		case 'D':
			// Download file
			$this->_checkoutput();
			header('Content-Type: application/x-download');
			header('Content-Disposition: attachment; filename="'.$name.'"');
			header('Cache-Control: private, max-age=0, must-revalidate');
			header('Pragma: public');
			echo $this->buffer;
			break;
		case 'F':
			// Save to local file
			$f = fopen($name,'wb');
			if(!$f)
				$this->Error('Unable to create output file: '.$name);
			fwrite($f,$this->buffer,strlen($this->buffer));
			fclose($f);
			break;
		case 'S':
