Abstract:
1. A printing apparatus which performs printing by discharging a liquid onto a printing medium, the printing apparatus comprising: a liquid discharge head which includes: a drive section which drives the discharge energy applying section; and a controller which controls the drive section based on a parameter with respect to a total number of times of driving of the discharge energy applying section; wherein, when one dot is formed on the printing medium by discharging the liquid from the nozzle, if a predetermined threshold value is not exceeded by the parameter, the controller controls the drive section to drive the discharge energy applying section so that a first discharge energy is applied to the liquid, and if the predetermined threshold value is exceeded by the parameter, the controller controls the drive section to drive the discharge energy applying section so that a second discharge energy which is lower than the first discharge energy is applied to the liquid; wherein the predetermined threshold value is based on a maximum drivable number of times of the discharge energy applying section; wherein the printing apparatus is selectively operable in one of a normal print mode to perform the printing with a predetermined resolution and a high-resolution print mode to perform the printing with a resolution higher than the predetermined resolution in the normal print mode; and wherein when the printing apparatus operates in the high-resolution print mode, the controller controls the device section to drive the discharge energy applying section, so that the first discharge energy which is higher than the second discharge energy is applied to the liquid, regardless of whether the predetermined threshold value is exceeded by the parameter or not.
