Print without print dialog

Hi

I want to print a document in Microsoft Word 2000 with the following code:

Sub Test ()
    Documents.Open FileName:="C:\doc\letter.doc"
    Set myMerge = ActiveDocument.MailMerge
    myMerge.OpenDataSource ("C:\doc\address.txt")
    If myMerge.State =  wdMainAndSourceAndHeader Or _
       myMerge.State = wdMainAndDataSource Then
        With myMerge.DataSource
            .FirstRecord = 1
            .LastRecord = 1
        End With
    End If
    With myMerge
        .Destination = wdSendToPrinter
        .Execute
    End With
End Sub

Execute prints the document, but always, the print dialog will be show.

Is is possible, to print without this dialog? How can I do that?

Thanks

Hans
