Well, that's why you're requested to supply your version information when
you submit a question
![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Apparently you're using one of the 11 versions
that preceded Office 2008... Or perhaps you aren't using a Mac at all - You
could be using one of the similar number of releases for Windows.
If that setting isn't available to you it means that you're using a version
that doesn't support printing of Backgrounds. The workaround is to obtain
the graphic you want to use as a background & insert it as a Watermark or as
an image in the Header.
