Abstract: A printing apparatus includes: a control unit configured to control a first heating process and a second heating process and configured to control the first heating process and the second heating process to be performed before a printing head starts printing an image on printing medium that is a printing target, wherein the second heating process is performed after the first heating process and before the printing head prints the image, and wherein a first target temperature in the first heating process is higher than a second target temperature in the second heating process.

Abstract: A printing apparatus includes a printhead with a plurality of print elements for generating energy used for printing an image on a print medium, a first temperature detection element and a second temperature detection element at positions different in a direction of a print element array in which the plurality of print elements are arrayed. The apparatus corrects a signal concerning a head temperature based on an output from the first temperature detection element, and corrects, based on the corrected signal concerning the head temperature, a signal concerning a head temperature output from the second temperature detection element.

Abstract: One embodiment of the present invention is a printing apparatus including: a print head having a printing element column in which a plurality of printing elements for ejecting ink from ejection ports is arrayed and performing printing on a printing medium by ejecting ink based on print data; a sensor that detects temperature of the print head; an acquisition unit configured to acquire information indicating a number of dots to be printed by printing elements corresponding to a predetermined area in the printing element column; and a control unit configured to control a printing operation of the print head based on temperature detected by the sensor and the number of dots acquired by the acquisition unit, and the printing apparatus performs printing on the printing medium by ejecting ink from the print head while the print head and the printing medium are moving relatively.
