Install the package libcupsimage2. I believe that will solve your problem.
It seems that cups no longer include this library by default, as of 2.3.1. Until I have a chance to modify the packages here to add a dependency explicitly on that library, it will need to be installed manually. This might still only be affecting a small number of people because several common cups drivers do explicitly depend on it, so many people probably have it installed even with cups 2.3.1.
