Abstract
A memory stores printing data. A CPU reads, from the memory, printing data on a target line to be printed subsequently and printing data on a plurality of immediately preceding lines, performs an arithmetic operation with respect to the read printing data to determine a history pattern, stores the determined history pattern in the memory, reads, from the memory, the history pattern of a history factor which is a dot exerting the influence of heat accumulation on a target dot to be printed subsequently, transmits the read history pattern to a thermal print head interface unit, and transmits a history timer value preliminarily allocated to the history factor to the thermal print head interface unit. The thermal print head interface unit drives a thermal print head based on the history pattern and on the history timer value.
