public static void SetPrinterPort(string printerName, string portName)
        {
            var oManagementScope = new ManagementScope(ManagementPath.DefaultPath);
            oManagementScope.Connect();

            SelectQuery oSelectQuery = new SelectQuery();
            oSelectQuery.QueryString = @"SELECT * FROM Win32_Printer 
            WHERE Name = '" + printerName.Replace("", "\") + "'";

            ManagementObjectSearcher oObjectSearcher =
               new ManagementObjectSearcher(oManagementScope, @oSelectQuery);
            ManagementObjectCollection oObjectCollection = oObjectSearcher.Get();

            foreach (ManagementObject oItem in oObjectCollection)

                oItem.Properties["PortName"].Value = portName;
                oItem.Put();
            }
