PrintDocument problem

I have a PrintDocument control that is printing my Desktop instead of the form.
Here is an excerpt of the code:

      Dim nullObject As System.Object = 0
      Dim str As String = ""
      Dim nullObjStr As System.Object = str
      ....
      AxWebBrowser1.Navigate("http://www.MySite.com/Report.aspx?OrderID=" & spParam , nullObject, nullObjStr, nullObjStr, nullObjStr)
       CaptureScreen()
       PrintDocument1.PrinterSettings.PrinterName = _prtNameInkJ
       PrintDocument1.Print()
       ........

 Private Declare Function BitBlt Lib "gdi32.dll" Alias "BitBlt" (ByVal hdcDest As IntPtr, ByVal nXDest As Integer, ByVal nYDest As Integer, ByVal nWidth As Integer, ByVal nHeight As Integer, ByVal hdcSrc As IntPtr, ByVal nXSrc As Integer, ByVal nYSrc As Integer, ByVal dwRop As System.Int32) As Long
   Dim memoryImage As Bitmap

   Private Sub CaptureScreen()
      Dim mygraphics As Graphics = Me.CreateGraphics()
      Dim s As Size = Me.Size
      memoryImage = New Bitmap(s.Width, s.Height, mygraphics)
      Dim memoryGraphics As Graphics = Graphics.FromImage(memoryImage)
      Dim dc1 As IntPtr = mygraphics.GetHdc
      Dim dc2 As IntPtr = memoryGraphics.GetHdc
      BitBlt(dc2, 0, 0, Me.ClientRectangle.Width, Me.ClientRectangle.Height, dc1, 0, 0, 13369376)
      mygraphics.ReleaseHdc(dc1)
      memoryGraphics.ReleaseHdc(dc2)
   End Sub

   Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
      e.Graphics.DrawImage(memoryImage, 0, 0)
   End Sub

But it does show the www.MySite.com in the Web browser control.
