[0051]figure 1 It is a schematic structure of the printing system of this invention.
[0052] A personal computer for generating print data (hereinafter referred to as “print data generating PC”) 101 is a print data generating device for generating print data to be printed by a plurality of printing devices 105 and 106 . The print data generation PC 101 is connected to personal computers (hereinafter referred to as “print data transfer PCs”) 103 and 104 for transferring print data through a communication interface having a hub 102 . Communication interfaces may include, for example, network cables, USB cables, and wireless LAN. In this example, the print data generated by the print data generation PC 101 is transferred to the print data transfer PC 103 or 104 through a network cable.
[0053] The print data transfer PCs 103 and 104 are connected to related printing apparatuses 105 and 106 through communication interfaces. The communication interface can use network, USB and ...

[0083] Figure 9A with 9B is a flowchart showing the data transmission and reception process between the print data generating PC 101 , the print data transmitting PCs 103 , 104 , and the printing apparatuses 105 , 106 in the second embodiment of the present invention. exist Figure 9A with 9B in, with Figure 7 The same processes are shown with the same reference numerals, and descriptions thereof are omitted.
[0084] The application 601 in the print data generating PC 101 acquires the engine number (printing device number) for the printing devices 105, 106 connected to the print data transmitting PCs 103, 104 after the print data generating process (step S702) starts (step S903) . That is, the print data generating PC 101 requests the print data transmitting PCs 103 , 104 to transmit the engine numbers of the printing apparatuses 105 , 106 . Upon receiving the engine numbers sent from the printing apparatuses 105, 106 (steps S940, S950), the print data transmitting PC...

[0089] Figure 10 A schematic view of a third embodiment of the invention is shown. The printing system in this example has five printer units or printing devices 116 (116-1 through 116-5). As in the previous embodiment, these printing devices are each connected to an associated print data transmitting PC (print data transmitting device) not shown in the figure, and these print data transmitting PCs are then connected to a print data generating PC not shown in the figure ( print data generator).
[0090] Each of the printing devices 116 has four inkjet print heads 811 (811Y, 811M, 811C, and 811K) for ejecting four inks (yellow (Y), magenta (M), cyan (C), and black, respectively. (K)). These print heads 811 are supplied with ink from corresponding ink cartridges 203 (203Y, 203M, 203C, and 203K).
[0091] The five printing devices 116 are supplied with image data corresponding to their positions. That is, the print data generating PC divides the image data to be printed on ...
