Data processing apparatus and data processing method

[0025]Then, an embodiment of the invention will be explained with the drawings. FIG. 1 is a structural diagram which shows an outline of a structure of a multifunction printer 20, i.e., an embodiment of the invention. FIG. 2 is a structural diagram which shows an outline of a structure of a CISM 50. The multifunction printer 20 of the embodiment has a controller 21 which entirely controls the apparatus, a network interface (I / F) 26 which performs communication with an external device, an operation panel 28 which has monitor and operation sections and can be variously operated by a user, a scanner unit 30 which optically reads a manuscript and produces image data and a printer unit 60 which prints an image on printing material.

[0026]The controller 21 is formed as a microprocessor centered around a CPU 22, and has a flash memory 23 in which various data processing programs, various data, various tables, etc., are stored, and a RAM 24 in which scan data or printing data is temporarily s
