A method of image processing for heat accumulation of a thermal printer refreshes grayscale output of printing pixels that lie in correction regions with smear phenomena caused by heat accumulation of a thermal printer. The actual grayscale output of the printing pixels of the correction regions is lower than the original grayscale output and the scale of correction of the grayscale output is gradually decreased to zero along the direction of printing. The method substantially eliminates the smear phenomena caused by heat accumulation and allows a thermal printer to provide better output.
