A display accesses an external server via a browser installed on an image processing apparatus, and displays on itself via the browser, a job instruction screen of the external server, based on screen data of the job instruction screen. When a user specifies a job, a job issuance requester requests the external server to issue the job and accordingly the external server issues the job. And a receiver receives the issued job and a job executor executes the received job. And then, a display controller makes the display to display a screen that matches a result of the receiver's job receipt and/or a job execution status of the job executed by the job executor.
