description	A printing apparatus (1) for printing using a printhead (30) including a plurality of nozzles (313) each configured to discharge ink and a plurality of sensors (306), corresponding to the plurality of nozzles, for detecting a discharge state of ink from the plurality of nozzles, judges a discharge state. More specifically, the apparatus prints, based on print data, an image by driving the printhead under a first drive condition to discharge the ink from the printhead to a first area (LI), discharges ink to a second area (L2) different from the first area by driving the printhead, based on inspection data, under a second drive condition different from the first drive condition, and judges a discharge state of each nozzle by monitoring an output from each sensor at a timing of driving the printhead under the second drive condition.
