A technology is provided that suppresses a noise that an image forming apparatus makes in the course of an operation thereof from interfering with a user who is watching television. When a printer 203 receives a print command, the printer 203 performs a print job as per a normal mode if a commercial is being displayed on a digital TV 201. If what is being displayed on the digital TV 201 is not the commercial, the printer 203 suspends the print job until the commercial begins to be displayed.
