Abstract

PURPOSE:To print stably, by a method wherein when a non-printing condition of a heat generating resistor is continued for a plurality of successive printing lines, the heat generating resistor is preheated in a printing line preceding the printing line in which the resistor is to be operated for printing, based on the printing history of the resistor and printing data for the next printing line. CONSTITUTION:A printing history storage part 14 stores printing data P1 constituted of '0' and '1', printing data P2 for the previous printing line, printing data P3 for the printing line preceding the previous printing line, and printing data P0 for the next printing line. When the condition where the printing data is '0' is continued for at least three printing lines, the temperature of a heat generating resistor is lowered to below a predetermined value. A printing power controlling part 13 supplies the heat generating resistor with an amount of electric power equivalent to 50% of optimum printing power in the printing line (P1) preceding the printing line in which the resistor is to be operated for printing, thereby raising the temperature of the resistor to about 50% of an optimum temperature. When the printing line in which the resistor is to be operated for printing is reached, an amount of heat equivalent to one half of the amount of heat supplied by the preheating is left in the resistor, and the controlling part 13 generates a printing pulse having a width corresponding to 100-50/2=75% of the optimum printing power, and supplied the pulse to the resistor of a thermal head 11. Accordingly, the heat generating resistor supplied with the pulse is brought to an optimum printing temperature, and favorable printing is performed.

In addition, when a large amount of power is supplied to the thermal head and the temperature of the heating resistor is rapidly raised, the base film of the thermal transfer ink ribbon, which has been made as thin as 3 μm in order to achieve high-speed printing and high resolution, becomes thinner. This has disadvantages in that the thermal head may melt and the life of the thermal head may be shortened.

On the other hand, in the printing power control unit 13, the printing data P2 of the 111th line of the relevant printing data supplied from the printing history storage unit 14, the printing data P3 of the 2nd line of previous printing data are both O", and the next line data Pa is 1". In this case, for example, 50% of the R-line printing power is supplied to the corresponding heating resistor of the thermal head 11 to perform preheating.In other words, as shown in FIG. When the print data is "O", the temperature of the heating resistor falls below a certain value as shown in FIG.
In such a case, one line before printing (Pl), 50% of the optimum printing power is supplied to the heating resistor as shown in FIG. %
It will be raised to a certain degree. In this case, the temperature of the heating resistor is lower than the optimum printing temperature Tp, so printing is not performed. In this state, when it comes to the printing line of this heating resistor, half of the residual heat from the previous line remains in this heating resistor, so the heating resistor is brought to the optimum temperature. Therefore, it is sufficient to supply 100-50/2=75% of the power to the printing power control section 1.
3, a printing pulse having a width corresponding to this printing power is generated and supplied to the corresponding heating resistor of the thermal head 11. Therefore, this heating resistor is brought to the optimum printing temperature, as shown in FIG. 2(C), and good printing is performed.

In the above state, if you want to print the next line as well, the heating resistor has already reached a certain temperature, so if you supply power equivalent to 50% of the optimal printing power, you can obtain the optimal printing temperature. It is possible to perform good printing.

According to the above embodiment, based on the stored printing history and the next line's print data, if multiple lines of -〇- are not printed consecutively, the heating resistor is preheated one line before printing. That's what I do. Therefore, during actual printing, the optimum printing temperature can be obtained using a power lower than the optimum printing power of the heating resistor, so stable printing can be achieved without using a high-power heating resistor as in the past. In addition, it is possible to extend the life of the heating resistor.
