HTML2PDF - Download and display pdf file to page

I am using HTML2PDF with Laravel 5.1. I have a problem with showing the pdf file on the page and downloading it to the server.

When I use this code, it shows the pdf file without problems:

        $pdf = $html2pdf->Output('', 'S'); 
        return response($pdf)
            ->header('Content-Type', 'application/pdf')
            ->header('Content-Length', strlen($pdf))
            ->header('Content-Disposition', 'inline; filename="sample.pdf"');

However, the above code does not save the file to the server. So I tried this:

        $filename = '\Report-' . $project->id . '.pdf';
        $output_path = base_path() . '\public\reports' . $filename;
        $pdf = $html2pdf->Output($output_path, 'F'); 
        return response($pdf)
            ->header('Content-Type', 'application/pdf')
            ->header('Content-Length', strlen($pdf))
            ->header('Content-Disposition', 'inline; filename="'.$output_path.'"');

I've tried this in Chrome and in Firefox but it does not display the document, it just downloads the file to the server. What am I doing wrong?
