Abstract: A printing apparatus has a moving carriage mounted on a printing head having a liquid ejection nozzle, a first cap at one end of a carriage movement range to cap the nozzle, a second cap at the other end of the range, to cap the nozzle, and a control unit having a first control in which first cap caps the nozzle or a second control in which the second cap caps the nozzle. When the carriage has anomalously stopped during printing, a recovery operation on the printing head after the first control execution is different from a recovery operation on the printing head after the second control is executed. The recovery operation includes preliminary liquid ejection at a timing other than printing, suctioning the liquid inside the first cap when the nozzle is capped by the first cap, and/or dipping the nozzle into the liquid supplied into the first cap.
