摘要： A thermal printer includes a thermal head, a drive data generation unit, a clock generation unit, and a drive data supply unit. The thermal head is configured such that a large number of heating elements divided into a plurality of blocks are mounted thereon, and is configured to input drive data for driving the large number of heating elements to the plurality of blocks in parallel in synchronization with a plurality of different first clock signals. The drive data generation unit is configured to generate a plurality of pieces of drive data for each of the plurality of blocks from print data and to output the plurality of pieces of drive data in synchronization with a plurality of second clock signals. The clock generation unit is configured to generate a plurality of clock signals whose phases are shifted from each other. The drive data supply unit is configured to take in the plurality of pieces of drive data, which are output from the drive data generation unit, in synchronization with the plurality of second clock signals and to supply the plurality of pieces of drive data to the thermal head in synchronization with the plurality of first clock signals.(Figure 2)

摘要： A thermal head control device (514) includes: a printing rate calculation range determination unit (142) configured to determine, as a printing rate calculation range, a range from a left-end energization dot to a right-end energization dot among energization dots present in printing data corresponding to heating elements (42) to be controlled among a plurality of heating elements (42) included in a thermal head (41); a printing rate calculation unit (143) configured to calculate a printing rate of the printing rate calculation range determined by the printing rate calculation range determination unit (142); an energizing time calculation unit (144) configured to calculate an energizing time for which a current is caused to flow through the heating elements (42) based on the printing rate calculated by the printing rate calculation unit (143); and an output unit (150) configured to output a control signal for driving the heating elements (42) to be controlled of the thermal head (41), based on the calculated energizing time.

摘要： When sub-images are sequentially transferred and connected together to form a larger image than would be possible with a single transfer operation, the occurrence of a color change in the overlapping region of the sub-images is suppressed and the width of the overlapping region is reduced as much as possible. Color image data are divided into image data of two sub-images containing an overlapping region and having edges that coincide for each color ink transferred to paper. Color values of the color image data in the overlapping region are converted by using a color conversion factor group created in advance for each position on the overlapping region so as to cancel out a color change that occurs in the overlapping region when the sub-images are transferred with one overlapping the other. The image data of the sub-images are corrected by adjusting converted color values in the overlapping region by using a correction factor for print density at each position on the overlapping region. A color image is formed by sequentially transferring the sub-images in accordance with corrected image data thereof so that the sub-images overlap at the overlapping region.

摘要： Provided is a printing control apparatus capable of avoiding weak print-out of a dot in one pulse application period as well as avoiding unclear print-out in other pulse application periods to follow the one pulse application period. In the printing control apparatus, there are arranged one pulse application period F1 of which from-start-to-end is series of sub-pulse application time S, main-pulse application time M1 and non-heating time C1 and other pulse application periods F2, F3... which follow one pulse application period F1 and of which from-start-to-end is repeated series of main-pulse application times M2, M3... and non-heating times C2, C3.... As temperature is higher, proportion of applied-for-sub-pulse energy amount to total energy amount in one pulse application period is made larger. As temperature is higher, proportion of applied-for-main-pulse energy amount to total energy amount in other pulse application periods F2, F3... that follow one pulse application period is made smaller.
