It "*Can*" be done, but it's more time, trouble & aggravation than it's
worth... especially if you're doc is more than just one sheet. And there's
no guarantee that it will be aligned properly when it prints - among other
things you have to put 1/2 in one H/F, 1/2 in the facing page H/F & try to
line them up across the spine.
You're better off to do a regular landscape page with columns - which will
still be a hassle.
You're _best_ off to use a page layout program such as MS Publisher for this
type of project. You can still type your copy in Word & place it in the
other file.
