The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.
A printing apparatus which prints an image on a printing medium by scanning a printhead while discharging ink from orifices by thermal energy of printing elements provided on the printhead, comprising:
