Abstract
An object is to provide a technique of calculating an ejection amount of an ink in accordance with a printing head. A printing apparatus includes: a printing head including an ejection port array in which multiple ejection ports to eject an ink are arrayed; a conveyer unit configured to convey a printing medium in a conveyance direction; and a controller unit configured to control the printing head. The controller unit executes processing to obtain the printing dot number based on printing data and processing to calculate an amount of the ink used in a case of performing printing based on the printing data by using different calculation methods between a case where a first printing mode is set and a case where a second printing mode is set based on the printing dot number and an ejection amount conversion factor corresponding to a temperature of the printing head.
