US Patent 7812990 Data processing apparatus and method

Provided are a data processing apparatus and method that make it possible to detect improper resource data that has been stored in a printer. The data processing apparatus, which is connectable to an image forming apparatus that refers to resource data when an image is formed, first acquires information relating to resource data that has been stored in the image forming apparatus and stores the information on a hard disk. Next, improper resource data is detected by control exercised by a CPU in the processing apparatus based upon the acquired information relating to the resource data. After prescribed processing is executed with respect to improper resource data that has been detected, information relating to prescribed resource data is provided to the image forming apparatus via a network controller.
