a processor configured to:

receive, through the communication interface, function identification information indicating a plurality of image processing functions available in a system including the image processing device;

determine whether or not each of the image processing functions is currently executable by the image processing device;

operate to install a supporting application for each of one or more image processing functions that are determined to be currently not executable by the image processing device; and

cause the display to display a screen including a first item corresponding to a first function of the image processing functions that is determined to be currently executable and a second item corresponding to a second function of the image processing functions that is determined to be currently not executable, wherein

the first item is displayed on the screen in a first display format, and the second item is displayed on the screen in the first display format when a supporting application for the second function is installed, and in a second display format that is less conspicuous than the first display format when the supporting application for the second function is not installed.

2. The device according to claim 1 , wherein lines are displayed in the first display format as solid lines and in the second display format as dashed or dotted lines.

3. The device according to claim 1 , wherein lines are displayed in the first display format in black color and in the second display format in gray color.

4. The device according to claim 1 , wherein

no item corresponding to a third function of the image processing functions that is determined to be currently not executable by the image processing device and for which a supporting application is not installed, is displayed on the screen.

5. The device according to claim 1 , wherein

upon login of a user into the image processing device, the processor operates to receive the function identification information, wherein the function identification information is associated with a user identification information of the user.

6. The device according to claim 1 , wherein

upon selection of the second item displayed on the screen in the second display format, the processor carries out a first process to install the supporting application for the second function, or a second process to cause information relating to one or more other image processing devices with which the second function is currently executable.

7. An image processing system comprising:

a master image processing device; and

a plurality of slave image processing devices, wherein

each of the slave image processing devices includes a communication interface, a display, and a processor configured to

receive, through the communication interface, function identification information indicating a plurality of image processing functions available in the image processing system;

determine whether or not each of the image processing functions is currently executable by the slave image processing device;

operate to install a supporting application for each of one or more image processing functions that are determined to be currently not executable by the slave image processing device; and

cause the display to display a screen including a first item corresponding to a first function of the image processing functions that is determined to be currently executable and a second item corresponding to a second function of the image processing functions that is determined to be currently not executable, and

the first item is displayed on the screen in a first display format, and the second item is displayed on the screen in the first display format when a supporting application for the second function is installed, and in a second display format that is less conspicuous than the first display format when the supporting application for the second function is not installed.

8. The system according to claim 7 , wherein

the master image processing device maintains a database that stores a user table with a plurality of entries, each entry including a user ID, a function ID, and a display method, and

upon login by a user in any one of the slave image processing devices, all of the entries including a user ID of the user are retrieved by the slave image processing device and the second display format is specified in one of the entries, which corresponds to the second function, as the display method of the second function.

9. The system according to claim 8 , wherein

the display method of one of the entries, which corresponds to a third function, specifies that an item corresponding to the third function is not to be displayed on the screen.

10. The system according to claim 8 , wherein

the display method of one of the entries, which corresponds to a fourth function, is not defined.

11. The system according to claim 8 , wherein

upon the login of the user into the one of the slave image processing devices, the processor of the one of the slave image processing devices carries out a first process to install a supporting application for the fourth function that is not executable without the application being installed or a second process to cause an item corresponding to the fourth function to be displayed on the screen or not displayed on the screen.

12. The system according to claim 11 , wherein

upon determining that the item corresponding to the fourth function is to be displayed on the screen, the processor of the one of the slave image processing devices determines a method of displaying the item on the screen.

13. The system according to claim 12 , wherein

upon determining the method displaying the item on the screen, the processor of the one of the slave image processing devices communicates with the master image processing device to update an entry corresponding to the user and the fourth function in the user table.

14. The system according to claim 7 , wherein

upon selection of the second item in one of the slave image processing devices, the processor thereof carries out a first process to install the supporting application for the second function, or a second process to cause information relating to one or more other image processing devices with which the second function is currently executable.

15. A control method carried out in an image processing device, comprising:

receiving, through a communication interface, function identification information indicating a plurality of image processing functions available in a system including the image processing device;

determining whether or not each of the image processing functions is currently executable by the image processing device; and

operating to install a supporting application for each of one or more image processing functions that are determined to be currently not executable by the image processing device;

displaying a screen including a first item corresponding to a first function of the image processing functions that is determined to be currently executable and a second item corresponding to a second function of the image processing functions that is determined to be not executable, wherein

the first item is displayed on the screen in a first display format, and the second item is displayed on the screen in the first display format when a supporting application for the second function is installed, and in a second display format that is less conspicuous than the first display format when the supporting application for the second function is not installed.

16. The method according to claim 15 , wherein

no item corresponding to a third function of the image processing functions that is determined to be currently not executable by the image processing device and for which a supporting application is not installed, is displayed on the screen.

17. The method according to claim 15 , wherein

upon login of a user into the image processing device, the function identification is received, wherein the function identification information is associated with a user identification information of the user.

18. The method according to claim 15 , further comprising:

upon selection of the second item displayed on the screen in the second display format, carrying out a first process to install the supporting application for the second function, or a second process to cause information relating to one or more other image processing devices with which the second function is currently executable.
