    string printername = printer.Properties["Name"].Value.ToString();
    if (printername == printerName)

        string workOffline = printer.Properties["WorkOffline"].Value.ToString().ToLower();
        printerStruct.WorkOffline = workOffline.ToLower() == "true";
        string jobCount = printer.Properties["JobCountSinceLastReset"].Value.ToString();
        printerStruct.JobCount = Convert.ToInt32(jobCount);
        Core.PrinterStatus ret = (Core.PrinterStatus)Convert.ToInt32(printer.Properties["PrinterStatus"].Value);
        printerStruct.PrinterStatus = ret;
        printerStruct.PrinterStatusString = ret.ToString();
