PROBLEM TO BE SOLVED: To take only valid data among received data. SOLUTION: When data transmitted from a host computer is valid data, the data comprises a start code, a command code, each command identification, data to each command and an end code. The valid data is transmitted to a label printer with a valid data code of not smaller than 2 bytes added to a head. Invalid data is transmitted to the label printer after an invalid data code of not smaller than 2 bytes is added to a head of the invalid data. At the label printer side, received data received after the valid data code is detected before the invalid data code is detected is taken inside as valid data. |
