摘要： A thermal printer has a thermal head including plural heating elements. The heating elements are arranged in an array in a main scan direction, are driven according to image data, for recording an image to thermosensitive recording paper moved in a sub scan direction. The recording paper has a size smaller in the main scan direction than the thermal head. The thermal printer includes two arrays of photo receptor elements for detecting two lateral edges of the recording paper, to determine effective heating elements in contact with the recording paper among the heating elements. A data correcting unit effects a correcting process to part of the image data for heating elements of a first group included in the effective heating elements. The first group contacts each of the two lateral edges and a near portion near to the lateral edge with reference to the main scan direction in the recording paper.

摘要： A head driver for thermal printing drives plural heating elements in a heating element array according to heating data for respectively the plural heating elements, to record dots of one line thermally by heating color thermosensitive recording material. A first data train is output, including gradation level data of gradation levels 0, 2, 4, . . . , 510. One-line image data for plural pixels in the one line is serially compared with the gradation level data in the first data train, so as to create even number gradation heating data in a serial signal form. Simultaneously with the first data train, a second data train is output, including gradation level data of gradation levels 1, 3, 5, . . . , 511. The one-line image data is serially compared with the gradation level data in the second data train, so as to create odd number gradation heating data in a serial signal form. After transfer to the head driver, the even number gradation heating data is converted into a parallel signal form. Also, the odd number gradation heating data is converted into a parallel signal form. The heating elements are supplied with respectively a drive signal by alternately reading the even and odd number gradation heating data.
