A printing device includes: an RFID reader including a reader antenna; a cassette mounting portion in which a plurality of types of cassettes can be selectively mounted; a memory storing correlations between the types of cassettes and standard ranges concerning a return energy; and a controller. Each cassette includes an RFID tag storing cassette information related to the cassette. The RFID tag includes a tag antenna configured to communicate with the reader antenna. Communication sensitivity between the reader antenna and the tag antenna when the cassette is mounted in the cassette mounting portion is different for each type of cassette. The controller performs: communicating via the RFID reader with the RFID tag of the cassette mounted in the cassette mounting portion; and determining whether a value of the return energy received by the RFID reader in the communicating falls within any one of the standard ranges indicated by the correlations.
