Abstract
A printing device includes a printing unit, a buffer, and a control unit. The control unit reads out data from the buffer as target data. When the read-out target data is a character code, the control unit determines whether the target data is a character code associated with a plurality of character forms or not. When the target data is the character code associated with the plurality of character forms, the control unit prefetches data stored in the buffer after the target data, as prefetched data, before printing the target data, and determines whether the prefetched data is a predetermined code or not. When the prefetched data is the predetermined code, the control unit selects a character form indicated by the predetermined code as a target character form and causes the printing unit to print a character represented by the target data, in the selected target character form.
