当我们将默认浏览器设置为chrome（除IE之外）时，从Windows应用程序打印html文件不起作用

Question

I have to print html file when user clicks on print button and it is working fine (prompts print dialog) when I set default browser as IE. If I change default browser to chrome or firefox other than IE, the code does not prompting print dialog instead it just opens html file in the browser. Can you please let me know what configuration I have missed in the below code?

            string TempFile = @"D:\test.html";    

            ProcessStartInfo Params = new ProcessStartInfo();
            Params.FileName = "iexplore.exe";
            Params.Arguments = TempFile;
            Params.UseShellExecute = false;
            Params.Verb = "print";
            Params.WindowStyle = ProcessWindowStyle.Hidden;
            Params.CreateNoWindow = true;
            Process.Start(Params);

Finally I got the solution for this issue. The below code works like a charm!!

using (Process exeProcess = new Process())
{
    string TempFile = @"D:\test.html";
    exeProcess.StartInfo.FileName = "rundll32";
    exeProcess.StartInfo.Arguments = @"system32\mshtml.dll,PrintHTML """ + TempFile + @"""";
    exeProcess.StartInfo.UseShellExecute = true;
    exeProcess.Start();
}
