Printer-friendly page displaying structural labels

In the last couple weeks something must have changed. Instead of correctly displaying only the heart of the page, it now shows the names of the CMS containers that make-up the whole page. Those containers are blank, but they squish the article itself into a narrow vertical strip. I've tried class="print-no" in the unwanted containers, but that had no effect.

Here is a sample page: http://www.osv.com/tabid/7621/itemid/9617/Stories-of-growing-up-with-Pope-John-Paul-II.aspx

Thanks,
