Abstract

A network device control method and apparatus for controlling various devices connected to a network cause a setting sheet that is for setting the environment of a device to be displayed on a screen so that the environment of the device may be set. A request for read-out of management information corresponding to each control on the setting sheet is transmitted to the network. If read-out of the management information succeeds, the information is set in the corresponding control and the display state thereof is enabled. If read-out fails and the reason is that the device does not support the date, then the name of the control is displayed in gray and the display is not displayed at all. If the function is one supported by the device, on the other hand, then the name of the control is displayed at ordinary brightness and the corresponding data is displayed in gray.

a step of setting a default value in the control and displaying the control in a third mode if a function corresponding to the control of the environment setting screen is supported by the device and, moreover, it has been determined by said discriminating step that said data is incapable of being acquired.

9. The method according to claim 8, wherein a name of the control and data corresponding to said control are displayed at ordinary brightness in the first mode.

10. The method according to claim 8, wherein a name of the control is displayed in a color or at a brightness approximating that of the background and display of data corresponding to said control is erased in the second mode.

11. The method according to claim 8, wherein a name of the control is displayed at ordinary brightness and a default value corresponding to said control is displayed in a color or at a brightness approximating that of the background in the third mode.

12. The method according to claim 8, wherein a name of the control is displayed in gray in the second mode and the default value is displayed in gray in the third mode.

13. The method according to claim 8, wherein the device is a printer.

14. The method according to claim 8, wherein the data is displayed in a combo box.

15. A network device control apparatus for setting the state of a device connected to the apparatus via a network, comprising:

display means for displaying an environment setting window which is for setting the environment of the device;

discriminating means for determining whether it is possible to acquire data corresponding to a control in the environment setting window displayed on said display means;

means for displaying the control in a first mode if said discriminating means has determined that said data is capable of being acquired;

means for displaying the control in a second mode when a function corresponding to the control in the environment setting window is not supported by the device; and

means for setting a default value in the control and displaying the control in a third mode if a function corresponding to the control in the environment setting window is supported by the device and, moreover, said discriminating means has determined that said data is incapable of being acquired.

16. The apparatus according to claim 15, wherein a name of the control and data corresponding to said control are displayed at ordinary brightness in the first mode.

17. The apparatus according to claim 15, wherein a name of the control is displayed in a color or at a brightness approximating that of the background and display of data corresponding to said control is erased in the second mode.
