Abstract
Disclosed is a printing apparatus for performing printing on a printing medium, based upon information transmitted from an external device, by causing a carriage, on which a printhead is mounted, to scan across the printing medium. The printhead includes any one of voltage detecting means for detecting at least one voltage among voltages at a node between a first power-supply wire and a monitor resistor element, a node between the monitor resistor element and a driving element, and a node between the driving element and a second power-supply wire; and any one of current application means for applying current to at least one of the nodes. At least one resistance is obtained, based upon applied current or detected voltage, from among resistance of the first and second power-supply wires, resistance of the monitor resistor element and resistance of the driving element, and the printhead is controlled based upon the resistance obtained.
