In an image-forming system, the first determining unit is configured to determine whether at least one image-forming device among the plurality of image-forming device is capable of performing the image print process. The second determining unit is configured to determine whether to restrict an image-forming device among the plurality of image-forming devices to execute the test print process based on a result of determination by the first determining unit. The restricting unit is configured to restrict the image-forming device to execute the test print process when the second determining unit determines to restrict the image-forming device to execute the test print process.
