Claims

[Scope of utility model registration request]

In a small color printer that performs printing by moving the main body of the device over recording paper to obtain sub-scanning, an ink ribbon is provided with three primary colors divided sequentially in the width direction, and a plurality of ink ribbons corresponding to the division intervals of the three primary colors of this ink ribbon are used. a thermal head equipped with a heating element; a means for converting color image data into density data of the three primary colors;
The apparatus comprises means for storing density data of each primary color, and means for setting driving times of respective heating elements of the thermal head based on the density data of each of the three primary colors stored by the storage means. A small color printer featuring
