Abstract
An inkjet printing apparatus includes a print head configured to print an image on a printing medium using a printing element configured to eject ink with thermal energy, a scanning unit configured to cause the print head to scan the printing medium, and a control unit configured to control scanning by the scanning unit and image printing by the print head based on an image printing instruction, wherein the control unit performs a control operation including executing a preliminary ejection to eject, from the print head, ink that does not contribute to image printing before an image is printed in one scanning operation, and determining an amount of ink to be ejected in the preliminary ejection based on a difference between a target temperature and a scanning start temperature, which is a temperature of the print head acquired in response to an instruction to start the one scanning operation.
