PDF Silent Printing not working in IIS using C# Process !!!

Hariharan Krishnamoorthi

Dear all,

I am trying to do autoprinting option using ASP.Net webapplication with some SSIS packages.

In my requirement, i need to auto print the pdf file with below codes. It is working when i am debugging in Visual studio. But when i deploy the files in IIS, It is not auto printing.

Please help me on this. Do i need to enable any properties in Windows server 2008.

Thanks in advance.

string arguments = arugumentValue; // /t "D:\\Temp_Report.pdf" "\\TestPrinter_one"
string executable="C:\\Program Files\\Adobe\\Reader 8.0\\Reader\\AcroRd32.exe"
int waitingTime = 18000;
ProcessStartInfo starter = new ProcessStartInfo(executable, arguments);
starter.CreateNoWindow = true;
starter.WindowStyle = ProcessWindowStyle.Hidden;
starter.UseShellExecute = false;
Process process = new Process();
process.StartInfo = starter;
process.Start();
process.WaitForExit(waitingTime); // hold the process for some seconds so that PDF
//files can be sent
process.CloseMainWindow();
process.Kill();
starter = null;
process = null;

The reason it's working inside Visual Studio is probably because the process runs with your credentials. When you run it in IIS, it uses the aspnet account. Maybe the account doesn't have access to the acrobat reader program, or doesn't have permission to use the printer (or both).
If you can't find a way to solve the permissions problem, consider using a different approach to print. If you use the LEADTOOLS imaging SDK (https://www.leadtools.com/), you can load the PDF without using Acrobat Reader, and you can then send the PDF pages as images to the printer. The C# code to that looks like this:
private RasterImage PDFImage = null;
private int currentPrintPageNumber;

private void menuItem1_Click(object sender, EventArgs e)
{
    using (RasterCodecs codecs = new RasterCodecs())
    {
        codecs.Options.Load.AllPages = true;
        // Load PDF as Image
        PDFImage = codecs.Load(@"Source.pdf");

        // Print
        using (PrintDocument document = new PrintDocument())
        {
            currentPrintPageNumber = 1;
            document.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);
            document.Print();
        }
        PDFImage.Dispose();
    }

}
private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
    PrintDocument document = sender as PrintDocument;
    RasterImagePrinter printer = new RasterImagePrinter();
    printer.PrintDocument = document;
    printer.SizeMode = RasterPaintSizeMode.FitAlways;
    printer.HorizontalAlignMode = RasterPaintAlignMode.Center;
    printer.VerticalAlignMode = RasterPaintAlignMode.Center;
    printer.PageRectangle = Rectangle.Empty;
    printer.ImageRectangle = Rectangle.Empty;
    printer.UseMargins = false;
    printer.Print(PDFImage, currentPrintPageNumber, e);
    currentPrintPageNumber++;

    if (currentPrintPageNumber <= PDFImage.PageCount)
        e.HasMorePages = true;
    else
        e.HasMorePages = false;
    printer.PrintDocument = null;
}
