Currently, I have a controller action that outputs a PDF (as a Response.OutputStream.Write()) and this is working just as it should.

However, I am interested in outputting another script section along with the PDF to “automatically print” (or simply perform a window.print();) on the PDF.

Is this possible, or is there another method to solve this issue that I may not be aware of?

Controller Action:

public ActionResult PrintPDF(string ID)
{
     //Population of Model

     //Output Result
     return PdfResult(model);
}

PDF Result:

var buffer = byteArrayStream.toByteArray();
response.OutputStream.Write(buffer, 0, buffer.Length);

//Is it possible to output something like the following:
response.Output.Write("<script type='text/javascript'>window.print();</script>");

    You will most likely not be able to mix PDF-data with JavaScript, so what you need to is embed the PDF-file using the <embed>-tag and then use javascript to print whatever is inside the <embed>-tag.

    Here’s some information that someone else got working. Basicly this is the code that is outputted (from the previous source but edited a little bit):

    <html>
    <body>
        <embed id="pdfToPrint" src ="@ViewData.PDFUrl" width="550" height="550"
        name="whatever">
        <script>
            var x = document.getElementById("pdfToPrint");
            x.click();
            x.setActive();
            x.focus();
            x.print();              
        </script>
    </body>

</html>
