Patent ID: 8514445

Claim:
An image processing system comprising: a client connected to a network which converts document data created by an application into print data in Page Description Language form; a controller connected to the network which develops the print data transmitted from the client through the network to image data of bit map form and transmits the image data; and an image processing apparatus connected to the controller which receives the image data of bit map form transmitted from the controller and memorizes the image data in a memory section of the image processing apparatus for printing the image data; wherein the image processing apparatus comprises: a management table for managing whereabouts of the image data; the memory section for memorizing the image data; and a control section for calculating a remaining ratio of nodes of the management table and a remaining ratio of the memory; wherein the control section selects one of the remaining ratio of nodes and the remaining ratio of the memory section where the selected remaining ratio is smaller than the other remaining ratio; and wherein the control section increases an interval of a notice to the controller that permits transmission of next image data to the image processing apparatus when the remaining ratio of nodes is selected and a remaining amount of nodes becomes less than or equal to a threshold value, or when the remaining ratio of the memory section is selected and a remaining amount of the memory section becomes less than or equal to a threshold value.
