The controller executes the first process once and then executes the second process. The first process is a process for back-feeding the continuous body, writing information to the RFID inlet, and then forward-feeding the continuous body until the RFID medium reaches the print start position. The second process is a process for stopping printing on the RFID medium halfway and writing information to the subsequent RFID medium following the RFID medium under printing when the RFID inlet of the subsequent RFID medium reaches the position allowing the communication with the antenna, and then resuming and completing printing on the RFID medium, printing on which was stopped halfway.
