An in-jet printing apparatus having a temperature detection device for outputting a signal in correspondence with a temperature, performs printing by using an ink-jet printhead which performs printing on a recording medium by discharging ink. A flag indicating whether acquisition of the temperature information is necessary or not is set, and the temperature information is obtained in accordance with the status of the flag, after the power on of the apparatus. The obtained temperature information is stored into a nonvolatile storage device. The temperature information can be obtained at appropriate timing in accordance with necessity, even if the power is interrupted during the operation. Thus a high-quality printed output can be obtained by performing a stable printing operation.
An ink-jet printing apparatus which performs printing on a recording medium by using an ink-jet printhead which performs printing by discharging ink, comprising:
A printhead control method in an ink-jet printing apparatus which has a temperature detection device to output a signal in correspondence with a temperature and which performs printing on a recording medium by using an ink-jet printhead which performs printing by discharging ink, said method comprising:
