Print pdf file without opening Print Dialog using windows form application

I want to print a PDF file (url) from windows application without opening print dialog.

I have tried the code bellow

        string pdfUrl="mysite.com/test.pdf";
        string printerName = "Microsoft Print To PDF";
        using (var client = new System.Net.WebClient())
        {
            client.Proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
            client.DownloadFile(pdfUrl, filePath);
        }

        ProcessStartInfo info = new ProcessStartInfo();
        info.Verb = "print";
        info.FileName = filePath;
        info.Arguments = "\"" + printerName + "\"";
        info.UseShellExecute = true;
        info.CreateNoWindow = true;
        info.WindowStyle = ProcessWindowStyle.Hidden;
        info.WorkingDirectory = Path.GetDirectoryName(filePath);

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

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

but getting error in p.Start(); bellow System.ComponentModel.Win32Exception: No application is associated with the specified file for this operation

What is missing?

Please suggest how to solve this.

My opinion is that you should use any third party library to printing PDFs. We are using following C# PDF library https://pdfium.patagames.com/c-pdf-library/

And yes, this is commercial library, so I don't know if I have a right to place a link here.

Here is a code to print PDF's without any user interaction:

public void PrintPdf()
{
    var doc = PdfDocument.Load("c:\test.pdf");
    var printDoc = new PdfPrintDocument(doc);
    PrintController printController = new StandardPrintController();
    printDoc.PrintController = printController;
    printDoc.Print(); // Print PDF document
}
