Where did you configure that? Can you try if configuring in cups itself http://localhost:631 works?
I confirm the issue since the first set of drivers. I use other kind of drivers in another machine MFC-P2500 Foomatic fixing the problem although printing problems on some characters as "g" "y" and others. That's a severe issue to face with.

If configuring the printer in CUPS doesn't work either it's not our bug, please report against your printer drivers, or maybe against CUPS filters. Thanks
