7. The apparatus according to claim 4 , wherein

the processor is configured to

adjust each of the job parameters each time a printing capability of one of the image forming apparatuses in the group is changed, and

perform a synchronization of the adjusted job parameters with the image forming apparatuses in the group.

8. The apparatus according to claim 1 ,

wherein

the processor is further configured to generate a second screen to be displayed on the display and by which the adjusted parameter can be further adjusted manually.

9. The apparatus according to claim 1 ,

wherein

the processor is further configured to generate third and fourth screens to be displayed on the display,

the third screen showing the adjusted parameter, and

the fourth screen by which an input for modifying the parameter is received.

10. An image forming system comprising:

a master image forming apparatus;

a plurality of slave image forming apparatuses connected to the master image forming apparatus and to each other over a network, wherein

a first image forming apparatus of a group of image forming apparatuses, which includes the master image forming apparatus and the slave image forming apparatuses, comprises

a display,

a memory that stores a plurality of sets of job parameters, each set having been used by one of a plurality of image forming apparatuses in a group to perform one of jobs, and

a processor configured to

generate a first screen to be displayed on the display, indicating a list of the jobs;

upon selection of one of the jobs via the first screen, determine a job parameter among the job parameters that has been used to perform the selected job and cannot be used by the first image forming apparatus,

adjust the determined job parameter so that the job parameter can be used by the first image forming apparatus, and

perform the selected job using the adjusted job parameter.

11. The system according to claim 10 , wherein

the first image forming apparatus is one of the slave image forming apparatuses in the group.

12. The system according to claim 10 , wherein

the image forming apparatus is the master image forming apparatus in the group.

13. The system according to claim 12 , wherein

the processor is further configured to, upon receipt of the plurality of sets of job parameters that have been used by one of the image forming apparatuses in the group via a network interface, adjust each of the job parameters so that the job parameter can be executed by any one of the image forming apparatuses in the group.

14. The system according to claim 13 , wherein

the processor adjusts each of the job parameters so that the job parameter can be executed by one of the image forming apparatuses having a lowest printing capability in the group.

15. The system according to claim 13 , wherein

the processor is configured to

adjust each of the job parameters each time a new image forming apparatus is added to the group or one of the image forming apparatuses is removed from the group, and

perform a synchronization of the adjusted job parameters with the image forming apparatuses in the group.

16. The system according to claim 13 , wherein

the processor is configured to

adjust each of the job parameters each time a printing capability of one of the image forming apparatuses in the group is changed, and

perform a synchronization of the adjusted job parameters with the image forming apparatuses in the group.

17. The system according to claim 10 , wherein

the processor is further configured to generate a second screen to be displayed on the display and by which the adjusted parameter can be further adjusted manually.

18. The system according to claim 10 , wherein

the processor is further configured to generate third and fourth screens to be displayed on the display,

the third screen showing the adjusted parameter, and

the fourth screen by which an input for modifying the parameter is received.

19. A method of sharing job parameters among a group of image forming apparatuses connected to each other over a network, the method comprising:

storing by one of the image forming apparatuses in the group a plurality of sets of job parameters, each set having been executed by another image forming apparatus in the group to perform one of jobs;

displaying a first screen indicating a list of the jobs;

upon selection of one of the jobs via the first screen, determining, by said one of the image forming apparatuses, a job parameter among the job parameters that has been used to perform the selected job and cannot be executed thereby and adjusting the determined job parameter so that the job parameter can be executed thereby; and
