iTextSharp PDF printing

Question

I\'m trying to create a method that will send a PDF file directly to my printer (causing the print dialog to appear).

Below is the code I\'ve been working on - most

Answer 1

I found a way to do this here: http://wskidmore.com/2011/03/pdf-initial-view-settings-itextsharp/

Based on that, I wrote this code:

private void PrintMenu()
{
    ...
    var notUriPath = Server.MapPath("~/" + filePathName);

    var doc = new Document();
    var reader = new PdfReader(notUriPath);
    using (var memoryStream = new MemoryStream())
    {
        var writer = PdfWriter.GetInstance(doc, memoryStream);
        doc.Open();

        // this action leads directly to printer dialogue
        var jAction = PdfAction.JavaScript("this.print(true);\r", writer);
        writer.AddJavaScript(jAction);

        var cb = writer.DirectContent;
        doc.AddDocListener(writer);

        for (var p = 1; p <= reader.NumberOfPages; p++)
        {
            doc.SetPageSize(reader.GetPageSize(p));
            doc.NewPage();
            var page = writer.GetImportedPage(reader, p);
            var rot = reader.GetPageRotation(p);
            if (rot == 90 || rot == 270)
                cb.AddTemplate(page, 0, -1.0F, 1.0F, 0, 0, reader.GetPageSizeWithRotation(p).Height);
            else
                cb.AddTemplate(page, 1.0F, 0, 0, 1.0F, 0, 0);
        }

        reader.Close();
        doc.Close();
        File.WriteAllBytes(notUriPath, memoryStream.ToArray());
    }

    theIframeForPrint.Attributes.Add("src", fullFilePath);
}

I hope it helps!

You want to add Javascript to the PDF to open the print dialog, not the web page (unless you really do want the web page print dialog, not the PDF print dialog). I have done this before, but not with iTextSharp; but a quick Google search should tell you how to add Javascript using iTextSharp to open the print dialog.
