A system includes an image processing apparatus that generates a print image based on a print job received from an external apparatus and an image output apparatus that prints using the print image. The image processing apparatus includes a determination unit that determines whether the image processing apparatus can communicate with the external apparatus and a transmission unit that, if it is determined that the image processing apparatus cannot communicate with the external apparatus, transmits to the image output apparatus an instruction to cause the image output apparatus to transition to a power saving state. The image output apparatus includes a reception unit that receives the instruction and a control unit that, if the reception unit receives the instruction, causes the image output apparatus to transition to the power saving state.
