DATA TRANSFER CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling data transfer between microcomputers, with which influences to be exerted upon other printing processing are reduced by efficiently transferring data concerning the transfer data of different capacities in the control of data transfer between microcomputers inside a printer with integrated plural microcomputers. SOLUTION: This data transfer control method performs switching to a data transfer control method for the unit of byte or data transfer control method based on a packet configuration corresponding to the capacity of data to be transferred.
