Answered my own question -- found it on the MS Office support site (imagine that!)...
You can save screen space in print layout view (print layout view: A view of a document or other object as it will appear when you print it. For example, items such as headers, footnotes, columns, and text boxes appear in their actual positions.) by hiding the white space on the top and bottom of each page and the gray space between pages.
Hide White Space button in print layout view
* Move the insertion point to the top or bottom of the page and click the Show White Space Button image or Hide White Space Button image button.
HideTip
* You can hide white space by default by clicking Options on the Tools menu and clearing the White space between pages check box on the View tab.
This is weird -- somehow the left ruler "in Print Layout View" is now showing only the area of the page without the header and footer - so I can't adjust the top or bottom margin by fiddling with the ruler on the left (the area that is normally blue). The only way I have found to override this is by going to header and footer view, then closing out of header and footer view. How does one undo this?
