ManagementObjectSearcher MgmtSearcher;

//Perform the search for printers and return the listing as a collection
MgmtSearcher = new ManagementObjectSearcher("Select * from Win32_Printer");
MgmtCollection = MgmtSearcher.Get();

foreach (ManagementObject objWMI in MgmtCollection)
{

    string name = objWMI["Name"].ToString().ToLower();

    if (name.Equals(printerName.ToLower()))
    {

        int state = Int32.Parse(objWMI["ExtendedPrinterStatus"].ToString());
        if ((state == 1) || //Other
        (state == 2) || //Unknown
        (state == 7) || //Offline
        (state == 9) || //error
        (state == 11) //Not Available
        )
        {
        throw new ApplicationException("hope you are finally offline");
        }

        state = Int32.Parse(objWMI["DetectedErrorState"].ToString());
        if (state != 2) //No error
        {
        throw new ApplicationException("hope you are finally offline");
        }

    }

}
