Get the HP printer status

I need to get the HP printer status, I have written this code:

using System;
using System.Collections;
using System.Linq;
using System.Management;
using System.Text;

namespace PrinterStatus
{
    class Program
    {
        private static int asd;
        private static string[] printerStatus = { "Other", "Unknown", "Idle", "Printing", "WarmUp", "Stopped Printing", "Offline" };
        private static string[] printerState = {"Paused","Error","Pending Deletion","Paper Jam","Paper Out","Manual Feed","Paper Problem", "Offline","IO Active","Busy","Printing",
            "Output Bin Full","Not Available","Waiting", "Processing","Initialization","Warming Up","Toner Low","No Toner","Page Punt", "User Intervention Required",
            "Out of Memory","Door Open","Server_Unknown","Power Save"};

        private static string printerName = "PDFPrt";

        static void lala()
        {
            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)
                {
                    if (property.Name.Equals("ExtendedPrinterStatus"))
                    {
                        if (asd != Convert.ToInt32(property.Value))
                        {
                            Console.WriteLine(">>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<");
                            Console.ReadKey(true);
                        }
                        Console.WriteLine(string.Format("{0}: {1}", property.Name, printerStatus[Convert.ToInt32(property.Value)]));
                        asd = Convert.ToInt32(property.Value);
                    }
                }
            }

        }
        static void Main(string[] args)
        {
            while (true)
            {
                lala();
            }
        }
    }
}

By the way, it's just test code :) So, I opened this program, before I open the program I have put a big file to print, but, the return information of printer is always idle. I think the correct answer is printing or busy. How I can solve this? ( maybe it's a wrong code :( )
