Maybe your printer has functionality to do that without needing to do
anything in Word. If not, you'll probably be best with an Open Macro in the
Template, but that may depend on how you're doing the printing and whether
or not it's a one-off exercise. I'm not sure off the top of my head but I
think that code for Watermarks may differ according to Word Version, so if
you need more help, please tell us what you're using, but here is a starting
point:
Application.ScreenUpdating = False
For Each s In ActiveDocument.Sections
For Each h In s.Headers
With h.Shapes.AddTextEffect(WhyMustISupplyThis, "Unofficial Copy", _
"Arial", 16, msoFalse, msoFalse, 0, 0)
.Line.Visible = False
With .Fill
.Visible = True
.Solid
.Transparency = 0.5
.ForeColor.RGB = RGB(192, 192, 192)
End With
With .WrapFormat
.AllowOverlap = True
.Side = wdWrapNone
.Type = wdWrapNone
End With
.Rotation = 315
.LockAspectRatio = True
.Width = s.PageSetup.PageWidth
.Left = wdShapeCenter
.Top = wdShapeCenter
.RelativeHorizontalPosition = wdRelativeVerticalPositionMargin
.RelativeVerticalPosition = wdRelativeVerticalPositionMargin
End With
Next h, s
