A printing apparatus capable of specifying the color material concentration in ink can discharge or suck the ink in a suitable amount for suppressing degradation in print quality or ink supply failure. The printing apparatus executes printing by scanning a printhead having an orifice to discharge ink. The printing apparatus includes a scanning unit which scans the printhead without discharging the ink to generate a discharge failure orifice, and a detection unit which detects the presence of the discharge failure orifice. The color material concentration in the ink is estimated on the basis of the number of times or the time of scanning without discharging the ink required until the detection unit detects the presence of the discharge failure orifice.
A printing apparatus for executing printing by scanning a printhead having an orifice to discharge ink, the apparatus comprising:
A control method for a printing apparatus which prints by scanning a printhead having an orifice to discharge ink, the method comprising:
A printing apparatus comprising:
