In a printing apparatus and a printing method, the frequency of an operation of detecting an inappropriate ejection state of each ejection port is increased, while allowing a decrease in throughput to be suppressed. The printing apparatus includes a first ejection state sensing unit for carrying out an ejection state sensing process in which determination of whether or not ejected droplets are normal is executed, during a single process, on all the ejection ports formed in the print head. The printing apparatus further includes a second ejection state sensing unit for carrying out the ejection state sensing process on the ejection ports in a part of a plurality of ejection port groups into which the plurality of ejection ports formed in the print head are divided.
A printing apparatus in which a print head including a plurality of ejection ports formed therein is capable of being mounted, a liquid being ejected through the ejection ports, the printing apparatus comprising:
A printing method of performing printing using a printing apparatus in which a print head including a plurality of ejection ports formed therein is capable of being mounted, a liquid being ejected through the ejection ports, the printing method comprising:
