How to get network printer name from IShellFolder ?

I have retrive system printer icons using IShellFolder (only way I found - is to use IShellFolder ), now I want to connect them with InstalledPrinters, but problem is - I can`t find way to find real printer name (such as "\\ServerName\PrinterName" ), with is different to display name of content of "Devices and printers" shell folder and only correct to use with PrinterSettings.

The code I have use to retrive printer icons and printer captions in "Devices and printers" shell folder:

Shell32.IShellFolder iDesktopFolder = Shell32.GetDesktopFolder();
try
{
    IntPtr pidlPrintersFolder;
    if (Shell32.SHGetFolderLocation(_hwndOwner, (int)Shell32.CSIDL.CSIDL_PRINTERS, IntPtr.Zero, 0, out pidlPrintersFolder) == 0)
        try
        {
            StringBuilder strDisplay = new StringBuilder(260);
            Guid guidIShellFolder = Shell32.IID_IShellFolder;
            IntPtr ptrPrintersShellFolder;
            iDesktopFolder.BindToObject(pidlPrintersFolder, IntPtr.Zero, ref guidIShellFolder, out ptrPrintersShellFolder);
            Object objPrintersShellFolder = Marshal.GetTypedObjectForIUnknown(ptrPrintersShellFolder, Shell32.ShellFolderType);
            try
            {
                Shell32.IShellFolder printersShellFolder = (Shell32.IShellFolder)objPrintersShellFolder;

                IntPtr ptrObjectsList;

                printersShellFolder.EnumObjects(_hwndOwner, Shell32.ESHCONTF.SHCONTF_NONFOLDERS, out ptrObjectsList);
                Object objEnumIDList = Marshal.GetTypedObjectForIUnknown(ptrObjectsList, Shell32.EnumIDListType);
                try
                {
                    Shell32.IEnumIDList iEnumIDList = (Shell32.IEnumIDList)objEnumIDList;
                    IntPtr[] rgelt = new IntPtr[1];
                    IntPtr pidlPrinter;
                    int pceltFetched;
                    Shell32.STRRET ptrString;
                    while (iEnumIDList.Next(1, rgelt, out pceltFetched) == 0 && pceltFetched == 1)
                    {
                        printersShellFolder.GetDisplayNameOf(rgelt[0],
                            Shell32.ESHGDN.SHGDN_NORMAL, out ptrString);
                        if (Shell32.StrRetToBuf(ref ptrString, rgelt[0], strDisplay,
                            (uint)strDisplay.Capacity) == 0)
                        {
                            pidlPrinter = Shell32.ILCombine(pidlPrintersFolder, rgelt[0]);
                            string printerDisplayName = strDisplay.ToString();

                            Shell32.SHFILEINFO shinfo = new Shell32.SHFILEINFO();
                            Shell32.SHGetFileInfo(this._pidl, 0, out shinfo, (uint)Marshal.SizeOf(shinfo), Shell32.SHGFI.PIDL | Shell32.SHGFI.AddOverlays | Shell32.SHGFI.Icon);
                            Icon printerIcon = (Icon)Icon.FromHandle(shinfo.hIcon).Clone();
                            Shell32.DestroyIcon(shinfo.hIcon);

                            // HOW TO GET PRINTER NAME (\\ServerName\printername) WITH IS DIFFERENT FROM A PRINTER NAME IN "DEVICES AND PRINTERS" SYSTEM FOLDER
                        }
                    }
                }
                finally
                {
                    Marshal.ReleaseComObject(objEnumIDList);
                }
            }
            finally
            {
                Marshal.ReleaseComObject(objPrintersShellFolder);
            }
        }
        finally
        {
            Shell32.ILFree(pidlPrintersFolder);
        }
}
finally
{
    Marshal.ReleaseComObject(iDesktopFolder);
}

Thanks
