  • Patent number: 10744790
    Abstract: In a printing device, a thermal head has heating elements and prints an image made up of line images. A memory stores sets of parameters, each set including one of first parameters and corresponding one of second parameters. The controller calculates an average consumed power with respect to a line image subject to calculation by dividing a total amount of consumed power by a period of time set in each first parameter, thereby providing average consumed powers for the sets of parameters. The total amount of consumed power is an accumulated consumed power consumed in the heating elements energized during printing in the period of time including a print timing of the line image subject to calculation. The controller sets a cycle time for printing the line image subject to calculation so that each average consumed power does not exceed an upper limit specified by corresponding one of second parameters.
