Abstract: PURPOSE:To facilitate to print with uniform density, to prevent breakage from occuring due to electric power in excess of allowable power and to eliminate the need for readjustment at the time of replacement, by a method wherein the resistance of a thermal printing head is detected during when a output is raised, and a voltage according to the detected resistance is set. CONSTITUTION:When a power source input voltage Ein is impressed on an output voltage stabilizing circuit 1, a safe low voltage irrespective of the resistance of a thermal head is supplied. A voltage drop E2-E1 generated in the resistance RH1 of the thermal printing head is discriminated by amplifiers OP2-OP4 of a discriminating circuit 5, and the information is inputted into data D1-D3 of a latch circuit 6. On the other hand, since the charging voltage level of a capacitor C2 is inputted into a C-terminal of the circuit 6, when the level reaches a threshold voltage of the C-terminal, the information inputted into the data D1- D is held, is transmitted to corresponding outputs Q1-Q3, and the outputs which have been at a low level at the time of resetting are switched to the information at this time. Namely, when the resistance RH1 of the printing head is high, all of the outputs Q1-Q3 are at a high level.

The charge value is compared with a predetermined basic lighting power value for calculating an insufficient power value or an excessive power value. IF the charged value is larger than a predetermined fundamental lighting power value, and furthermore, the insufficient integrated power value is zero, the load is increased. If the charge value is smaller than the predetermined basic lighting power value, the load illumination lights corresponding to the fundamental lighting power value are lit. The power control is practiced so as to fill the then insufficient power value with the excessive power value on days, when the charge value was larger than the fundamental lighting power value.
