 Getting Printer Status/Comment like PrintDialog

I am working on a custom form that works like PrintDialog.

What I need is the Status, Type, Where, and Comment information.  Visual
inheritance would be ideal, but the class is sealed.

I have tried various ways to get PRINTER_INFO_2 but all are rather messy.

Any help would be appreciated,
John

 Getting Printer Status/Comment like PrintDialog
sometimes we cannot get away from pinvoke.  here is the code for exercising.

using System;
using System.Runtime.InteropServices;

public class Win32
{
    [DllImport("winspool.drv", CharSet=CharSet.Auto, SetLastError=true)]
    public static extern bool OpenPrinter(string printer, out IntPtr
handle, IntPtr printerDefaults);

    [DllImport("winspool.drv")]
    public static extern bool ClosePrinter(IntPtr handle);

    [DllImport("winspool.drv", CharSet=CharSet.Auto, SetLastError=true)]
    public static extern bool GetPrinter(IntPtr handle, UInt32 level,
IntPtr buffer,
        UInt32 size, out UInt32 sizeNeeded);

    [StructLayout(LayoutKind.Sequential, CharSet=CharSet.Auto)]
    public struct PRINTER_INFO_2
    {
        public string pServerName;
        public string pPrinterName;
        public string pShareName;
        public string pPortName;
        public string pDriverName;
        public string pComment;
        public string pLocation;
        public IntPtr pDevMode;
        public string pSepFile;
        public string pPrintProcessor;
        public string pDatatype;
        public string pParameters;
        public IntPtr pSecurityDescriptor;
        public UInt32 Attributes;
        public UInt32 Priority;
        public UInt32 DefaultPriority;
        public UInt32 StartTime;
        public UInt32 UntilTime;
        public UInt32 Status;
        public UInt32 cJobs;
        public UInt32 AveragePPM;
    }

public class printdlg
{
    [STAThread]
    public static void Main(string[] args)
    {
        string printer = "\\\\server\\printer";
        IntPtr handle = IntPtr.Zero;
        if(!Win32.OpenPrinter(printer, out handle, IntPtr.Zero))
        {
            System.Console.WriteLine("Fail OpenPrinter: {0}",
Marshal.GetLastWin32Error());
            return;
        }
        UInt32 level = 2;
        UInt32 sizeNeeded = 0;
        IntPtr buffer = IntPtr.Zero;
        Win32.GetPrinter(handle, level, buffer, 0, out sizeNeeded);
        buffer = Marshal.AllocHGlobal((int)sizeNeeded);
        if(!Win32.GetPrinter(handle, level, buffer, sizeNeeded, out
sizeNeeded))
        {
            System.Console.WriteLine("Fail GetPrinter: {0}",
Marshal.GetLastWin32Error());
            return;
        }
        Win32.PRINTER_INFO_2 info = (Win32.PRINTER_INFO_2)
            Marshal.PtrToStructure(buffer, typeof(Win32.PRINTER_INFO_2));
        System.Console.WriteLine("status:\t{0}", info.Status);
        System.Console.WriteLine("type:\t{0}", info.pDriverName);
        System.Console.WriteLine("where:\t{0}", info.pLocation);
        System.Console.WriteLine("comment:\t{0}", info.pComment);
        Marshal.FreeHGlobal(buffer);
        Win32.ClosePrinter(handle);
    }
