ABSTRACT:
An image forming system includes an image producing apparatus that produces image data and an image forming apparatus that prints the image data. The image producing apparatus produces the image data, and detects from the image data usage information indicative of an amount of consumable required for printing the image data. Then, the image producing apparatus sends the usage information to the image forming apparatus. The image forming apparatus adds the usage information to an accumulated amount of consumable to update the accumulated amount of consumable. When the accumulated amount of consumable exceeds a threshold, the image forming apparatus sends to the image producing apparatus setting information that specifies the settings of the image producing apparatus such that an image is formed without an accumulated amount consumable exceeding an upper limit. The image producing apparatus performs its setting based on the setting information.
