Abstract
A printing apparatus, including a conveyor, a liquid ejection head with nozzles, a carriage, a carriage movement mechanism, and a controller, is provided. The controller executes a printing operation including a parameter determining process and an ejection timing determining process. In the parameter determining process, a value to a correction parameter is determined. In the ejection timing determining process, ejection timing to eject liquid through the nozzles is determined based on the value to the correction parameter. In the ejection timing determining process, the controller determines the ejection timing by shifting the ejection timing to be at least one of later and earlier than a reference timing for a time length corresponding to the value to the correction parameter. In the parameter determining process, the controller provides a different value to the correction parameter for the scan-printing action in the second unit-printing process depending on the nozzle shift amount.
