Abstract
A method of printing a test pattern in a printer includes printing a related-information acquisition pattern as the test pattern in a particular state by driving a plurality of drive elements of a liquid ejection head to eject a liquid droplet from a plurality of nozzles based on a temperature detected by a temperature sensor. The related-information acquisition pattern is a pattern for acquiring related information relating to at least one of an ejection amount and a liquid droplet landing position of the liquid droplet ejected from each of the plurality of nozzles. The liquid droplet landing position is a position at which the liquid droplet ejected from each of the plurality of nozzles lands on a recording medium. The particular state is a state where a temperature difference between the temperature detected by the temperature sensor and an actual temperature of the liquid ejection head is constant.
