Anebo:
The following code will set the printer to duplex and print a document. This can be particularly useful in Word 2002 for a document set up as a booklet using the Bookfold option in File/Page Setup. The pages can then be stapled in the middle and folded to make the booklet.
Sub PrintDuplexBooklet()
Dim iDuplex As Long
iDuplex = GetDuplex 'save the current setting
SetDuplex 3 'set for vertical binding
ActiveDocument.PrintOut Background:=False
SetDuplex iDuplex 'restore the original setting
End Sub
