Although you said CUPS wasn't updated so it should be unlikely, but may be worth re-applying settings to enable sharing (on server) and browsing (on client).
I actually removed and reinstalled the printers with system-config-printer on each machine, with no change.
At this point I've decided to give up on it for the moment since the remote printers do work as long as I configure them manually on each machine. I plan to update both machines to Centos 6 and hopefully the problem will just go away at that point.
A huge thank you to everyone who replied with suggestions! And a further thank you to everyone who thought about this problem, even if you didn't reply. Your time thinking about it is also appreciated.
I sincerely appreciate the huge depth of knowledge that's represented on this mailing list.
