<P>PROBLEM TO BE SOLVED: To make original character image data remaining on an ink ribbon used for printing to be illegible. <P>SOLUTION: An overwriting character image data generation means 43 for generating overwriting character image data to be overwritten on original character image data comprises an overwriting character frame demarcating section 43e for demarcating a plurality of overwriting character frames in a row region corresponding to sizes of characters in the row region detected by means of a row detection section 43a and a row region detection section 43b, and a character data addition section 43f that generates additional character data by adding character data to each other in at least two or more overwriting character frames which are sequentially adjacent to one overwriting character frame in the plurality of overwriting character frames as overwriting character data to be overwritten to the original character data in one overwriting character frame to obtain the additional character data by each frame in the plurality of overwriting character frames. The overwriting character image data generation means 43 further comprises an overwriting character image data output section 43g that outputs each of the additional character data obtained by the character data addition section 43f to a thermal head 15 as the overwriting character image data with respect to the row region. <P>COPYRIGHT: (C)2008,JPO&INPIT |
