Word should save the current setting with the document. For more, see http://word.mvps.org/faqs/general/SaveViewAndZoom.htm. If this doesn't
do what you want, you could try the following automacros (put them in
a global template, such as normal.dot):
Sub AutoOpen()
ActiveWindow.View.Type = 3 'Print layout view
ActiveWindow.View.Zoom.PageFit = wdPageFitBestFit
End Sub
Sub AutoNew()
ActiveWindow.View.Type = 3 'Print Layout view
ActiveWindow.View.Zoom.PageFit = wdPageFitBestFit
End Sub
