A printing apparatus measures the voltage between two electrodes in an ink tank based on an electric current supplied to one of the two electrodes, and compares the measured voltage with a first threshold voltage.

According to results of these two comparisons, control is performed to supply the electric current, re-measure the voltage between the two electrodes, and re-inspect a residual ink amount. In a case where accurate determination is suspected, the presence/absence of ink is determined by re-inspection.
