PURPOSE:To obtain a printing uniform as well as sharp at the rising by controlling the heating OFF time of the thermal head according to the current and subsequent bit information applied or to be applied to the thermal head to eliminate deviation in the recording dot writing unit. CONSTITUTION:While the recording cycle (tcy) is fixed, the heating OFF time tOFF is changed according to the current and subsequent bit information to always keep the heating end timing constant. To be more specific, when printing dot information changes from absence to presence, the tOFF1 shall be shortened while when the printing dot information-presence state continues, the tOFF2 is lengthened. |
