PURPOSE:To prevent the damage of a printing head even when a power supply is again closed at a time when the temp. of the printing head is high by detecting the number of printing dots in the relation between a time and the temp. of the printing head and controlling printing on the basis of the detection result. CONSTITUTION:A microcomputer 1 controls printing and refers to the correction data stored in a correction data table 3 on the basis of counting control, the subtraction operation from the count value of a counter 2 at every predetermined counting, the reading control of the output of an A/D converter 7 and the temp. of a printing head and has the functions of correction operation performing the correction of a subtrahend value for substraction and printing operation limiting control limiting printing operation until the printing head is radiated. The microcomputer 1 reads the printing data sent out through an interface 8 to store the same in a printing buffer 9. |
