1. A printing apparatus comprising:
a printing head including an ejection port array in which a plurality of ejection ports to eject an ink are arrayed;
a conveyer unit configured to convey a printing medium in a conveyance direction;
a controller unit configured to count a printing dot number based on printing data, perform a first calculation for calculating an amount of the ink used in a case of performing printing based on the printing data in a case where a first printing mode is set based on the printing dot number, and perform a second calculation different from the first calculation for calculating an amount of the ink used in a case of performing printing based on the printing data in case where a second printing mode is set,
wherein the controller unit is configured to (1) in a case where the first printing mode is set, refer to a first region greater than a second region of an ejection surface provided with the plurality of ejection ports as a unit of the first calculation, and (2) in a case where the second printing mode is set, refer to the second region smaller than the first region as a unit of the second calculation.
