<p>PURPOSE:To prevent erroneous operation which occurs due to rise of temperature and prevent a user from determining a breakdown by a printing device wherein all printings are performed when temperature of a thermal head reaches a first temperature and a normal printing is stopped till below the first temperature when the temperature of the head reaches a second temperature higher than the first temperature at completion of the printing and generates damage in the head and erroneous operation. CONSTITUTION:When there is an output T1 from a temperature sensor 12, a printing of a page which is under printing presently ends. When there is not an image data of a next page, the printing ends as it is. When there is the image data of the next page and there is not an output T2 from the sensor 12, reading of the image data of the next page starts and printing operation for the next page follows. As time elapses until a thermal head starts the printing of the next page and the temperature of the head lowers, stopping of the printing is unnecessary. When there is the output T2 from the sensor 12, as there are erroneous operation and inside damage of the head, a CPU 8 does not read out the image data of the next page from an image memory 11 until the temperature lowers and the output T1 from the sensor 12 runs out, and stops printing operation of a recording section K.</p> |
