Abstract: A printing apparatus includes a printing unit configured to print an image on a print medium, an acquiring unit configured to acquire temperature information of the printing unit, and a control unit configured to control the printing unit so as to start relative scanning in a case where a temperature that is indicated by the temperature information has reached a print permission temperature. The print permission temperature in a first print mode whose speed at a time of a constant speed in relative scanning is a first speed is a first temperature. The print permission temperature in a second print mode whose speed at the time of the constant speed is a second speed that is faster than the first speed is a second temperature that is lower than the first temperature.

Abstract: In order to make it less likely for the accuracy of determination of the ejection state of a liquid ejection head to be low, a liquid ejection apparatus sets a determination threshold for determining an ejection state of the liquid ejection head using first energy, the determination threshold being set based on a first output value outputted from the output unit in an event where the heat generating resistance element is driven with the first energy in an ejection state in which the liquid is ejected from an ejection port and a second output value estimated to be outputted from the output unit assuming the heat generating resistance element is driven with the first energy in a non-ejection state in which the liquid is not ejected.

Abstract: An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Abstract: A liquid ejection apparatus includes: a liquid ejection head that ejects a liquid from an ejection port; and a cap movable to a closed position at which the cap covers the ejection port and an open position which is separated from the closed position and at which the ejection port is open. The liquid ejection apparatus further includes: a recovery unit configured to perform a recovery process of recovering liquid ejection performance of the liquid ejection head; and a determination unit configured to determine whether abnormal termination occurred with the cap at the open position when the liquid ejection apparatus resumes operating. In a case where the determination unit determines that the abnormal termination occurred, the recovery process is controlled based on a temperature obtained by a temperature obtaining unit.
