PROBLEM TO BE SOLVED: To improve the throughput by reducing the transfer amount of the data transmitted or received by an image buffer and to effectively utilize the image buffer. SOLUTION: This printing circuit 1 comprises a printing controlling circuit 11, an image buffer 12, a driving signal producing circuit 13, and a printing head 14, wherein the driving signal producing circuit 13 comprises a data register 131, a resetting means 133 for transmitting a resetting signal to the data register, and a driving signal producing part 132 for producing a driving signal for operating a plurality of pins or a plurality of nozzles of the printing head. The resetting means 133 resets the data register in the case the data register 131 converts all the printing data stored in the image buffer to pin/nozzle driving data so as to produce null data in the data register. |
