Stefan has answered your question, but in addition...
If you do not want the Hidden text to print go into Word> Preferences> Print
& clear the check for Hidden.
If you want the content to remain in the document but no longer be Hidden
either select the text & go to Format> Font to remove the Hidden attribute
or modify the Style if that's how it was applied.
Also, there is a separate newsgroup for Mac Word as well as for the other
Mac Office software. Although many things are the same/similar there are
some that are quite different, so you'd do better to post any Mac Office
related questions there. Go to the Mactopia web site & click the Forums link
in the topmost navigation bar or use this link:

You may find accessing newsgroups using a newsreader (such as Entourage) to
be a bit more effective & less confusing. If you're interested look here:
