Next, referring to FIG. 1(b), reference numeral 8 denotes a communication control unit that includes the method according to the present invention and a general facsimile communication procedure;
1 is a received data separation unit that separates and outputs a print command code and encoded data based on the RTC signal contained in the received data transmitted according to FIG. 4; 10 is input from the received data separation unit 9. Each of the diagrams shows a code image converter that generates print data according to a print instruction code. Here, for the image data print command code, the corresponding part is generated in a white state according to the header part of the command code shown in FIG. Further, data indicating the starting position 1 and size of the white portion is generated in the layer where the white portion appears.
