a controller operable, when the second judging unit determines to limit execution of image forming of the image data, to limit execution of the image forming by the image forming unit, and operable, when the second judging unit determines not to limit execution of image forming of the image data, to instruct the image forming unit to execute image forming of the image data.
2. The image forming apparatus according to claim 1 , further comprising:
a generation unit operable to generate history information relating to an execution history of the image forming unit; and
a first storage operable to store the history information and user identification information corresponding to the history information.
3. The image forming apparatus according to claim 2 , wherein
the controller is operable to instruct the generation unit to generate the history information and to store in the first storage the generated history information with the user identification information of the unregistered user corresponding to the generated history information.
4. The image forming apparatus according to claim 2 , wherein
the second storage is operable to store therein limit information corresponding to each of the user identification information of a registered user and the user identification information of the unregistered user, and
the setting unit is operable to set the execution limitation information based on the history information and the limit information for each of the registered user and the unregistered user identification information.
5. The image forming apparatus according to claim 4 , wherein
the user identification information of the each of the registered user and the unregistered user is a PIN (Personal Identification Number).
6. The image forming apparatus according to claim 2 , wherein
the history information includes a number of image-formed sheets,
the limit information includes an upper limit of the number of image-formed sheets,
the setting unit includes:
a comparison determination unit operable to compare the number of image-formed sheets and the upper limit and to determine whether the number of image-formed sheets is less than the upper limit, for each user, and
an execution unit operable to set, when the comparison determination determines that the number of image-formed sheets is not less than the upper limit, the execution limitation information as a prohibition of execution of the image forming.
7. The image forming apparatus according to claim 1 , wherein
the image data includes apparatus identification information of the information processing apparatus,
the image forming apparatus further comprises:
an acquisition unit operable to acquire the apparatus identification information from the image data, when the first judging unit determines that no user identification information is attached the image data and the second judging unit determines to permit execution of image forming of the image data; wherein
the controller stores the history information with the acquired apparatus identification information in the first storage, and
the setting unit sets the execution limitation information of the unregistered user corresponding to the apparatus identification information.
8. The image forming apparatus according to claim 7 , wherein
when the acquisition unit acquires the apparatus identification information, the second judging unit determines, based on the execution limitation information corresponding to the apparatus identification information, whether or not to permit execution of image forming of the image data.
9. The image forming apparatus according to claim 7 , wherein
the acquisition unit acquires the apparatus identification information from the image data and the second judging unit determines, based on the execution limitation information corresponding to the apparatus identification information, whether or not to permit execution of image forming of the image data.
10. The image forming apparatus according to claim 7 , wherein
the apparatus identification information is a name of the information processing apparatus.
11. The image forming apparatus according to claim 7 , wherein
the apparatus identification information is a user name of the user using the information processing apparatus.
12. An image forming system, comprising:
an image forming apparatus including:
a reception unit operable to receive image data with user identification information from information processing apparatus; and
an image forming unit configured to form images based on the image data,
a server including:
a server acquisition unit communicatable with the image forming apparatus and operable to acquire the user identification information from the image forming apparatus;
a storage operable to store registered user identification information for registered users; and
a setting unit operable to set in the image forming apparatus execution limitation information for unregistered users, the execution limitation information relating to limitation on the image forming of the image forming apparatus, wherein
the image forming apparatus further comprises:
a first judging unit operable, when receiving an image data by the reception unit, to determine whether user identification information attached to the image data correspond to one of the registered user identification information, with reference to the storage;
a second judging unit operable, when the first judging unit determines that the user identification information attached to the image data does not correspond to one of the registered user identification information, to determine, based on the execution limitation information that is set for the unregistered users, whether or not to limit execution of image forming of the image data; and
a controller operable, when the second judging unit determines to limit execution of image forming of the image data, to limit execution of the image forming by the image forming unit and operable, when the second judging unit determines not to limit execution of image forming of the image data, to instruct the image forming unit to execute the image forming of the image data.
13. A image forming method comprising:
determining whether user identification information attached to an image data corresponds to one of registered user identification information stored in a storage;
determining, when the user identification information attached to the image data does not correspond to one of the registered user identification information in the storage, whether or not to limit execution of image forming of the image data, based on execution limitation information that is set for unregistered users;
instructing an image forming unit to execute the image forming of the image data by an image forming unit, when it is determined that execution of image forming of the image data is not limited; and
