If you have Word 2000 or later, you can create the document at full size and
use "4 pages per sheet" in the Print dialog. Otherwise, use a 2 x 2 table or
2 columns with appropriate spacing, the same content repeated in each column
(with appropriate spacing between).
Much the easiest way to do this, however, is in Publisher, if you have it.
You can set up the document once and print it four times on the page.
