Are you using the Hardy packages? Shortly after 1.1.2 came out, someone made this comment in another thread: > BTW, if you're on 64 bit ubuntu,, better stay on 1.1.1 OR fiddle a bit with build... changes on cups made printers disappears, but JUST for ubuntu 64 bit. > It seems it's solved on latest git. I don't know any more about it than that (I use openSUSE). It may have nothing to do with your problem, but it might be worth downgrading to 1.1.1 just to check.
