Image-processing system enabling user to use a plurality of communicably connected image-processing apparatuses, image-processing apparatus, function execution authorizing method, and function execution authorizing program embodied in computer readable medium

摘要

In order to facilitate the setting of functions executable in each of a plurality of image-processing apparatuses that are communicably connected to one another, each of the MFPs, which are communicably connected to one another, stores registered-user information including at least user identification information in each HDD. When an operated terminal among the plurality of MFPs receives user identification information, the operated terminal judges whether its HDD stores registered-user information including the received user identification information. When judging in the affirmative, the operated terminal permits execution of the functions possessed by the operated terminal. When judging in the negative, the operated terminal acquires, from the MFP (home terminal) that stores registered-user information including the received user identification information, the function information of the home terminal, and permits execution of the functions, among the functions defined in the function information of the home terminal, that are also possessed by the operated terminal.
