c# printer properties WMI

Question

Hello I have this code to retreive printer properties:

string printerName = "PrinterName";
string query = string.Format("SELECT * from Win32_Printer " 
                                + "WHERE Name LIKE '%{0}'",
                             printerName);

ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
ManagementObjectCollection coll = searcher.Get();

foreach (ManagementObject printer in coll)
{
    foreach (PropertyData property in printer.Properties)
    {
          Console.WriteLine(string.Format("{0}: {1}", 
                                          property.Name, 
                                          property.Value));
    }
}

But properties I need always return the same:

PrinterState:0

PrinterStatus:3

Basically I need this to check if printer is out of paper. What I think would be: PrinterState: 4

Tested on wxp-86 and w7-64 return the same, .Net 4.0

Thank you.

According to msdn , Paper Out=5

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {
            try
            {
                string printerName = "PrinterName";
                ManagementObjectSearcher searcher = 
                    new ManagementObjectSearcher("root\\CIMV2", 
                    "SELECT * FROM Win32_Printer "
                     + "WHERE Name LIKE '%{0}'", printerName);); 

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_Printer instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("PrinterStatus: {0}", queryObj["PrinterStatus"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}
