A printing apparatus includes a unit (151, 161) which counts the number of drive pulses applied to a print head and accumulatively stores the number of the drive pulses from the start of initial use of the printing head, and a unit (152, 162) which measures a temperature of the printing head and a time elapsed at the temperature in conjunction with each other, and stores a temperature history. The printing apparatus controls a timing of ink ejection from the printing head and an amount of ink to be ejected by adjusting a width of the drive pulses dependently on stored contents (a use history of the printing head) to maintain a stable image quality by adequately preventing ejecting characteristics and dot forming locations on a printing medium from being varied due to a use history of the print head. <IMAGE> |
