Printing in windows forms

Question

I have a windows forms application where I am trying to print something but if there is no actual printer (not xps or something else) I want to show a message box which indicates that there is no actual printer. So in short I want them to print if there is a real printer set as default in the current computer which leads me to check if the default printer is real.

You can do this using System.Management. Use the following class to solve your problem:

public class MyClass
{

    static void printProps(ManagementObject o, string prop)
    {
        try
        {
            Console.WriteLine(prop + "|" + o[prop]);
        }
        catch (Exception e)
        {
            Console.Write(e.ToString());
        }
    }

    [STAThread]
    static void Main(string[] args)
    {
        ManagementObjectSearcher searcher = new
        ManagementObjectSearcher("SELECT * FROM Win32_Printer where Default=True");

        string printerName = "";
        foreach (ManagementObject printer in searcher.Get())
        {
            printerName = printer["Name"].ToString().ToLower();
            Console.WriteLine("Printer :" + printerName);
            printProps(printer, "WorkOffline");
            //Console.WriteLine();
            switch (Int32.Parse(printer["PrinterStatus"].ToString()))
            {
                case 1: Console.WriteLine("Other"); break;
                case 2: Console.WriteLine("Unknown"); break;
                case 3: Console.WriteLine("Idle"); break;
                case 4: Console.WriteLine("Printing"); break;
                case 5: Console.WriteLine("Warmup"); break;
                case 6: Console.WriteLine("Stopped printing"); break;
                case 7: Console.WriteLine("Offline"); break;
            }
        }
    }
}
