PROBLEM TO BE SOLVED: To provide a new thermal head with a function of stably controlling at all times heat build-up temperature and accompanying energy generated in the head, by solving the traditional problems in complicated operations wherein erasing has been performed in a thermostat instead of a printer due to the absence of a suitable erasing mechanism when printing is performed with new contents after heating and erasing the printed surface printed through a laser printer using a special toner. SOLUTION: Cost-effective and high-speed operations and facilitation in printing/erasing operation have been realized by mounting a new thermal head unit for the performance of erasing function in the laser printer and by printing immediately after erasing within the printer.
