How Do I Print From Internet Explorer Without Raising a Confirmation Dialog?

NOTE: the concepts presented in this article are now considered obsolete possibly because better alternatives are available.

Update!! 11-29-2005
There seems to be a problem with the code presented in this article, so don't rely on it work anymore. When you click the print button you get an error and nothing gets printed.

So far, I haven't been able to isolate the problem or come up with a solution. It looks like this problem is caused by some security mechanism in Windows XP Service Pack 2. I haven't tested various versions of IE and Windows XP yet, but I am sure it doesn't run on IE 6, SP2 with Windows XP SP2 (well, it doesn't run on *my* IE 6, SP2 with Windows XP SP2 ;-) )

In some scenario's, it could be useful if you were able to print a page from within the browser, without the Print dialog popping up, and without the user confirming the print operation.
It is possible to have your page printed automatically, without the dialog. It's a bit tricky, it works on IE only and you may need to lower your security settings, but it does work. Copy and paste the following code to a new HTML document, run it in your browser and hit the print button. The page gets printed on the default printer without a confirmation dialog.
  <script language="JavaScript" type="text/javascript">
    DA = (document.all) ? 1 : 0
    function HandleError()
      alert('\nNothing was printed. \n\nIf you do want to print ' +
          'this page, then\n click on the printer icon in the ' +
          'toolbar above.')
      return true;
    <input type="button" value="Print Page" onClick="window.print();">
  <script language="VBScript">
    Sub window_onunload()
      On Error Resume Next
      Set WB = nothing
      On Error Goto 0
    End Sub
    Sub Print()

      On Error Resume Next

      If DA Then
        call WB.IOleCommandTarget.Exec _
      End If

      If Err.Number <> 0 Then
        If DA Then
          Alert("Nothing Printed :" & err.number & " : " & err.description)
        End if
      End If
      On Error Goto 0
    End Sub
    If DA Then
    End If
    document.write("<object ID=""WB"" width=0 height=0 classid="" clsid:")
    document.write(wbvers & """> </object>")

Where to Next?
