C# send file (pdf, html or rtf) to printer

Question

I have a problem with printing the files in C #. How to print any file with the possibility of two-sided printing.

        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();

But it does not satisfy me, because I can not here set the print parameters. How can I do this using the PrintDocument class?

I using Spire PDF to convert pdf to image.

            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("e:\\proba1.pdf");

            BitmapSource source;
            Bitmap bmp;

            for (int i = 1; i < pdf.Pages.Count + 1; i++)
            {
                source = pdf.SaveAsImage(i);
                bmp = SourceToBitmap(source);
                bmp.Save(string.Format("result-{0}.png", i), ImageFormat.Png);
            }

But, I get a error:

Error   1   Cannot implicitly convert type 'System.Drawing.Image' to 'System.Windows.Media.Imaging.BitmapSource'    C:\Users\Łukasz\documents\visual studio 2013\Projects\WpfApplication1\WpfApplication1\MainWindow.xaml.cs    90  26  FileMonitor

Answer 1

You can use Free .NET PDF Library (free, on visualstudiogallery). Convert the PDF to Image and print this with PrintDocument ....

Answer 2

For Spire.NET (from tutorial)

PdfDocument doc = new PdfDocument(); 
doc.LoadFromFile("sample.pdf"); 
Bitmap bmp = doc.SaveAsImage(0); 
bmp.Save("convertToBmp.bmp", ImageFormat.Bmp);
