This invention relates to precisely obtaining a head temperature free from influence of a signal transferred to a printhead, without slowing down the printing speed. In a printing apparatus which includes a printhead including a plurality of printing elements and a temperature sensor, and divides the plurality of printing elements into a plurality of blocks to print while performing division driving of the plurality of printing elements for each block, the head temperature is detected as follows. First, one printing period determined by a printhead driving frequency is divided into an active period required for the division driving and an inactive period required for A/D-converting an analog temperature data signal from the temperature sensor. While a signal required to drive the printhead is transferred in the active period, a digital signal A/D-converted from the temperature data signal from the printhead is read in the inactive period. |
