Abstract: A printing apparatus includes: a mount portion that removably supports a cassette configured to contain a printing medium and including a cassette storage; a printing device configured to draw the printing medium from the cassette and perform printing on the printing medium; and a controller. The controller performs: when the printing apparatus is in a required state in which medium information stored in the cassette storage of the cassette mounted on the mount portion is required, executing obtaining-communication for obtaining the medium information from the cassette, each time when a first cycle has elapsed; and when the printing apparatus is in a non-required state in which the medium information stored in the cassette storage of the cassette mounted on the mount portion is not required, inhibiting execution of the obtaining-communication or executing the obtaining-communication each time when a second cycle greater than the first cycle has elapsed.
