send pdf file to a printer - print pdf

Question

I'm programming a web application with Visual Studio 2010 (C#). I want to send a PDF (saved in my computer) to a printer when I click a button.

To create the PDF I used iTextSharp. I tried this, but it just opens Adobe Reader:

               proc.StartInfo.FileName = @"C:\Archivos de programa\Adobe\Reader10.0\Reader\AcroRd32.exe";
               proc.StartInfo.Arguments = String.Format(@"/p /h {0}", pdfFileName);
               proc.StartInfo.UseShellExecute = false;
               proc.StartInfo.CreateNoWindow = true;

               proc.Start();

Thank you in advance!!!

Solution

this has already been asked and answered here: How can I send a file document to the printer and have it print?

The code that was used:

private void SendToPrinter()
    {
        ProcessStartInfo info = new ProcessStartInfo();
        info.Verb = "print";
        info.FileName = @"c:\output.pdf";
        info.CreateNoWindow = true;
        info.WindowStyle = ProcessWindowStyle.Hidden;

        Process p = new Process();
        p.StartInfo = info;
        p.Start();

        p.WaitForInputIdle();
        System.Threading.Thread.Sleep(3000);
        if (false == p.CloseMainWindow())
            p.Kill();
    }

it basicly opens a "hidden" pdf-reader, tells it to print, waits for it to finish then close it down

This is good solution, but what if I want to print document with manual printer setting?

WaitForInputIdle() has no effect. It seems that p is in idle-Mode after Start(). Only the sleep for 3 seconds allows Adobe to finish the spooling. This might be a problem for large documents.

It doesn't work no more on Windows 8+

Although it is printing the file without any issue, but p.WaitForInputIdle(); doesn't return any value and the program remain stuck on this line of code
