Abstract
There is an object of providing a printing apparatus which can restrict a variation in ejection characteristic of an ink droplet due to a temperature change of a printing head to restrict degradation in an image. The printing apparatus adjusts temperatures of the print head to first and second temperature so as to measure ejection characteristics of the print head at the first and second temperature. Then, a driving condition is generated based on the measured ejection characteristics and a printing is performed based on the measured ejection characteristics.
