My orders.print.php, like everything else about my install, if FAR from stock. But I think I see the issue. Copy the print.css section about page-break and add it to the #printLabel section. The one at the bottom is to break off customer notes to a second page.

Not quite the answer you were looking for, but if you create a new zone, give it an abreviation like MTY (empty),and in the name field add about 4 blank spaces.
You can save this as an empty county which also appears at the top of your county list so easy to find.
I suppose a lazy customer could also use this though.
