Try this :

[DllImport("winspool.Drv", EntryPoint = "DocumentPropertiesW", SetLastError = true,
            ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        static extern int DocumentProperties(IntPtr hwnd, IntPtr hPrinter,
        [MarshalAs(UnmanagedType.LPWStr)] string pDeviceName,
        IntPtr pDevModeOutput, ref IntPtr pDevModeInput, int fMode);
        [DllImport("kernel32.dll")]
        static extern IntPtr GlobalLock(IntPtr hMem);
        [DllImport("kernel32.dll")]
        static extern bool GlobalUnlock(IntPtr hMem);
        [DllImport("kernel32.dll")]
        static extern bool GlobalFree(IntPtr hMem);
        private void OpenPrinterPropertiesDialog(PrinterSettings printerSettings)
        {
            IntPtr handle = (new System.Windows.Interop.WindowInteropHelper(this.fullScreenPrintWindow)).Handle;
            IntPtr hDevMode = printerSettings.GetHdevmode(printerSettings.DefaultPageSettings);
            IntPtr pDevMode = GlobalLock(hDevMode);
            int sizeNeeded = DocumentProperties(handle, IntPtr.Zero, printerSettings.PrinterName, pDevMode, ref pDevMode, 0);
            IntPtr devModeData = Marshal.AllocHGlobal(sizeNeeded);
            DocumentProperties(handle, IntPtr.Zero, printerSettings.PrinterName, devModeData, ref pDevMode, 14);
            GlobalUnlock(hDevMode);
            printerSettings.SetHdevmode(devModeData);
            printerSettings.DefaultPageSettings.SetHdevmode(devModeData);
            GlobalFree(hDevMode);
            Marshal.FreeHGlobal(devModeData);
        }

[DllImport("winspool.Drv", EntryPoint = "DocumentPropertiesW", SetLastError = true,
            ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        static extern int DocumentProperties(IntPtr hwnd, IntPtr hPrinter,
        [MarshalAs(UnmanagedType.LPWStr)] string pDeviceName,
        IntPtr pDevModeOutput, ref IntPtr pDevModeInput, int fMode);
        [DllImport("kernel32.dll")]
        static extern IntPtr GlobalLock(IntPtr hMem);
        [DllImport("kernel32.dll")]
        static extern bool GlobalUnlock(IntPtr hMem);
        [DllImport("kernel32.dll")]
        static extern bool GlobalFree(IntPtr hMem);
        private void OpenPrinterPropertiesDialog(PrinterSettings printerSettings)
        {
        //fullScreenPrintWindow in this example is a window. 
            IntPtr handle = (new System.Windows.Interop.WindowInteropHelper(this.fullScreenPrintWindow)).Handle;
            IntPtr hDevMode = printerSettings.GetHdevmode(printerSettings.DefaultPageSettings);
            IntPtr pDevMode = GlobalLock(hDevMode);
            int sizeNeeded = DocumentProperties(handle, IntPtr.Zero, printerSettings.PrinterName, pDevMode, ref pDevMode, 0);
            IntPtr devModeData = Marshal.AllocHGlobal(sizeNeeded);
            DocumentProperties(handle, IntPtr.Zero, printerSettings.PrinterName, devModeData, ref pDevMode, 14);
            GlobalUnlock(hDevMode);
            printerSettings.SetHdevmode(devModeData);
            printerSettings.DefaultPageSettings.SetHdevmode(devModeData);
            GlobalFree(hDevMode);
            Marshal.FreeHGlobal(devModeData);
        }

//Somewhere in you code show the dialog using this : 

            PrinterSettings settings = new PrinterSettings();
            settings.PrinterName = CurrentPrinter.FullName;
            OpenPrinterPropertiesDialog(settings);
