Abstract

A printing apparatus prints by discharging ink to a transfer member from a first printhead, discharging a transfer accelerator to the ink from a second printhead, and transferring an image formed on the transfer member to a print medium. When inspecting a discharge state of each of plural nozzles provided in each of the first and second printheads, the apparatus controls the second printhead so as to discharge the transfer accelerator from at least one nozzle of the second printhead to a discharge area of the transfer member to which the ink is discharged by the first printhead for inspection of the discharge states of the plural nozzles of the first printhead, while inspecting a discharge state of a nozzle different from the at least one nozzle of the second printhead by discharging the transfer accelerator from the nozzle.
