I am working on project. In my System when I run the project it is running nicely, but after uploading it to my domain when I check, then it displays the error like:

"Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application."

if (printDialog.ShowDialog() == DialogResult.OK)
{
    printDocument.PrinterSettings = printDialog.PrinterSettings;
    printDocument.PrintPage += OnPrintPage;
    foreach (var file in myarray)
    {
        System.Drawing.Image img = Bitmap.FromFile(file);
        Bitmap bmp = new Bitmap(img);
        ResuletImage = bmp;
        printDocument.DefaultPageSettings.Landscape = true;
        printDocument.PrinterSettings.PrinterName = default;
        printDocument.DocumentName = file;
        printDocument.Print();
    }
}
