The second identification information ID2 is a QR code.

Next, in step S105, the determination unit 113 determines whether the first identification information ID1 and the second identification information ID2 do not match. For example, the determining unit 113 determines whether the character string obtained by converting the QR code of the first identification information ID1 is inconsistent with the character string obtained by converting the QR code of the second identification information ID2.
If the determination unit 113 determines that the first identification information ID1 matches the second identification information ID2 (step S105; NO), the process proceeds to step S115.

If the first control unit 11 determines that the process of changing from the first character code system CD1 to the second character code system CD2 has failed (step S111; YES), the process advances to step S117.
Then, in step S117, the notification unit 116 notifies that the first character code system CD1 cannot be changed to the second character code system CD2. The notification unit 116 prints characters on the print medium M indicating that the first character code system CD1 cannot be changed to the second character code system CD2. After that, the process ends.
