In a printing device capable of exchanging a plurality of printing elements which correspond to a plurality of character sets, respectively, at least two of the character sets having common character data, the device sequentially receives text data including character data, and identification code data for identifying one of the character sets, the identification code data being put prior to the succeeding character data for indicating the character set used in preparing the succeeding character data differs from that used for the preceding character data, it is discriminated one by one whether the succeeding character data received by the data receiving means is one of the common character data in the character set used in preparing the preceding character data, and the device is controlled such that the identification code data is not stored in a print buffer until the succeeding character data is discriminated not to be one of the common character data.
