Image forming apparatus and image processing method for limiting the communication between print controller and print engine based on load of the print engine

摘要

The state of an engine control section is detected, it is determined on the basis of the state of the engine control section whether communication between a printer controller and the engine control section can be performed, and control is performed to limit communication. Even when a plurality of controllers are present, a composite operation is allowed without excessively increasing the communication load.
