US Patent 7692806 Image processing system and method

When a user system requests an image processing apparatus to perform a color correction processing and an image processing, an authentication processing is performed between the user system and the image processing apparatus. The user system outputs drawing data and print options to the image processing apparatus, which then performs RIP processing of the drawing data, and an accounting processing for the RIP processing is performed. Subsequently, a print processing of the image data supplied by performing the RIP processing is performed on a printer. Charging for the print processing is conducted.
