Image processing system, process execution control apparatus, and image generation-output control apparatus

An image generation-output control apparatus employable for an image processing system for sequentially executing a plurality of processes, the image generation-output control apparatus capable of controlling an execution of an image generation-output operation, the image processing system including a process execution control apparatus capable of controlling an execution of the plurality of processes, the process execution control apparatus including a control-side drawing information generator useable for generating drawing information to be referred by an image forming apparatus when the image forming apparatus performs an image generation-output operation based on information of a target image to be used for the image generation-output operation, the image generation-output control apparatus comprising:

• an output-side drawing information generator corresponding to the control-side drawing information generator,
• wherein when the control-side drawing information generator excludes an execution result of a designated process item from execution results of a plurality of process items to be executed for generating the drawing information to generate designated-information-excluded image information based on the information of the target image, and outputs the designated-information-excluded image information, the output-side drawing information generator acquires the designated-information-excluded image information, and the output-side drawing information generator executes the plurality of process items based on the generated designated-information-excluded image information when process contents of the designated process item is set at the image generation-output control apparatus.
