11. The method of claim 1 , further comprising, when the information about the generated pop-up event is transmitted to a plurality of target devices, processing the generated pop-up event by using a user command that is first received from among user commands input from the plurality of target devices.

12. The method of claim 1 , wherein a first mobile device of the devices connected to the image forming apparatus is a different type of mobile device than a second mobile device of the devices connected to the image forming apparatus.

13. The method of claim 1 , wherein the information about the generated pop-up event is not transmitted to at least one non-target device from among the devices connected to the image forming apparatus based on the determination.

14. An image forming apparatus comprising:

at least one memory storing instructions;

a controller including at least one processor configured to execute the instructions stored in the at least one memory to cause the following to be performed:

after a monitored pop-up event is generated, identify a current state of each of a plurality of devices that are connected to the image forming apparatus based on at least one of a state of an application executable on a foreground of a respective device of the plurality of devices and a state of another application executable on a background of the respective device of the plurality of devices, and

determine at least one target device that is to be requested to display a pop-up window indicating the monitored pop-up event has been generated from among the plurality of devices connected to the image forming apparatus based on the identified state of the each of the connected devices; and

a network interface configured to transmit information about the generated pop-up event to the at least one target device determined by the controller from among the devices connected to the image forming apparatus.

15. The image forming apparatus of claim 14 , further comprising storage for pre-storing rules relating a type of pop-up event and a state of a mobile device for determining the at least one target device after the pop-up event is generated,

wherein the controller determines the at least one target device by using the pre-stored rules.
