Since that page specifically says "Permission granted to photocopy for personal use only," I don't see a problem with making a copy of that page and saving it as a pdf. (or asking someone to do it for you: http://home.uchicago.edu/~swilbur/dnd/CombatCards.pdf)
WotC really should make it standard practice to supply PDFs of every document that they say is free to photocopy. Seems like basic level of service these days.
