Вы можете добавить макрос, подобный следующему, к модулю кода ThisDocument глобального шаблона (например, Normal.dotm):
Private Sub Document_Open()
With ActiveWindow
'Reduce flickering while changing settings
.Visible = False
'Switch to a single view pane
.View.SplitSpecial = wdPaneNone
.View.Type = wdPrintView
.ActivePane.View.Zoom.PageFit = wdPageFitFullPage
'Restore the window now that we're finished
.Visible = True
End With
End Sub
