    摘要： Dynamic division drive of a thermal printer is simplified to reduce the number of signal lines, and history control drive is made efficient to shorten time necessary for data transfer. The thermal printer comprises a heating array 1 for printing split up into blocks and arranged in a line, a plurality of driver units 2, each for driving a block of the heating array 1 separately from other blocks, and a logic circuit 3 for controlling the driver units 2. The logic circuit 3 comprises a block specifying means 31 for specifying one driver unit 2 or two or more driver units 2 to be operated according to block selection data BDAT inputted from an external source. Only the specified driver units 2 are simultaneously operated according to a single strobe signal DST inputted from the external source. Further, the logic circuit 3 comprises a data operation means 33 for internally originating history data based on print data HDAT inputted from the external source. Further, the logic circuit 3 comprises a transfer control means 32 for transferring the history data and the print data HDAT efficiently to each of the driver units 2 to carry out history control drive of each of the blocks of the heating array.
