4.5. Main Control Board
4.5.1. Data Flow
The following indicates the data flow when communicating with the host computer using these interfaces.
(1) The print data transfer by the host computer is received by Parallel I/F, USB I/F or Network I/F ( for KX-P7110
only ) controlled by CPU ASIC ( IC1 ), and stored in the system memory.The system memory is also controlled
by the CPU ASIC ( IC1 )
(2) The print data stored in the system memory is analyzed and rendered into an image ( ex. the arrangement and
generation of fonts and images ) by CPU ASIC ( IC1 ), and the image data is stored in the system memory.
(3) The image data stored in the memory is converted into video data by the CPU ASIC ( IC1 ) internal Video Data
Generator ( VDG ) and the video data is outputted to the ECU ( Engine Control Unit ) in responseto requests.
