An event notification system in which a terminal is notified of events generated in devices via a network

An event notification system includes a terminal and devices coupled thereto via a network that process jobs provided from the terminal. The device includes a database in which a subscription including an event type and a notification address is registered on the basis of a notification registration request from the terminal. In the device, an event generator generates an event with event data indicating a status change within the device. Given the status change of a job, a value indicating a requestor of the job process is included in the event data. When the event data includes the requester, an event notification manager sends a notification to the notification address in the subscription including the values of the status change and the requester, and sends the notification to the notification address in the subscription including the value of the status change.
