Access Denied when calling PrintQueue.Pause() method in C#.net

Question

I'm trying to pause a windows 7 print queue using C#.NET visual studio 2008. I have full administrator rights but when I run the following code to Pause the Queue it says Access is Denied. Please help me.

        LocalPrintServer lps = new LocalPrintServer(PrintSystemDesiredAccess.AdministrateServer);
        //PrintServer lps = new PrintServer("\\\\NOTEBOOK-CI3", PrintSystemDesiredAccess.AdministratePrinter);
        lps.Commit();
        PrintQueue queue = lps.GetPrintQueue(listBox1.SelectedItem.ToString());
        if (!queue.IsPaused)
            queue.Pause();

        queue.Commit();
        lps.Commit();

I'm not sure but have you tried to change LocalPrinterServer to PrinterServer? Take a look at http://www.visualbasicask.com/visual-basic-language/printqueuepause.shtml.
He had the exact same problem and could solve it by using PrintSystemDesiredAccess.AdministrateServer (which you do use). The only difference is that you're using LocalPrinterServer instead of PrinterServer.
