Inkjet printing apparatus, control method therefor, and program

摘要

In an inkjet printing apparatus which holds a printhead for performing printing by using ink supplied from an ink tank via an ink supply channel, the ink tank has a tank-side terminal for detecting the presence state of ink in the ink tank. The printhead has a head-side terminal for detecting the presence state of ink in the printhead. The printing apparatus detects at least one of the presence state of ink in the ink tank, printhead, and ink supply channel by selecting a terminal used for detection between the tank-side terminal and the head-side terminal.
