Hi Stefan,

But if you hide the highlighting from view, it won't print either
(and vice versa), or am I missing some new option in Word 2010 here?

yes, you are right. The setting will hide/unhide highlighted text on
screen as well as on paper at the same time.
So JFW has to change the option just before printing, and just after
printing.
He can use this macro (provided by VBA help):

Sub ToggleHighlight()
ActiveDocument.ActiveWindow.View.ShowHighlight = _
Not ActiveDocument.ActiveWindow.View.ShowHighlight
End Sub
