In a printing apparatus including a circulation system circulating a liquid, a volatile component included in the liquid evaporates from an ejection opening and thus characteristics of the liquid involving with concentration, viscosity and the like change. The invention provides a printing apparatus including: a page wide type liquid ejection head that includes an ejection opening ejecting a liquid, a print element generating energy for ejecting a liquid, and a pressure chamber having the print element provided therein; a cap that covers the ejection opening; and a circulator configured to circulate the liquid so that the liquid passes through the pressure chamber, wherein a circulation of the liquid is started after the cap is opened and the circulation of the liquid is stopped in a case where an image forming operation of ejecting the liquid from the ejection opening on the basis of a job is ended. 在包括使液体循环的循环系统的打印设备中，液体内包含的挥发成分从喷出口挥发，因而涉及浓度和粘性等的液体特性会变化。本发明提供种打印设备，其包括：页宽型液体喷出头，其包括喷出液体的喷出口、产生喷出液体用的能量的打印元件以及内
