After some more experiments I'm beginning to think it is more to do with the printer than with CUPS - this is a Samsung ML-2571N. I tried some other image files and they didn't give multiple copies. On the other hand, sometimes the printer just blinks and doesn't print anything, but if I turn it off and on again it then preints OK. So perhaps it is the memory becoming full?
In fact, this happens with ALL files, not just image ones.
