• Data check is performed for the “0” portion (shaded in the right table) to categorize the data into
4 patterns from c to f. If the data does not match the 4 patterns, command processing will
be aborted.
• The data categorized into the 4 patterns from c to f is converted, as shown by the left table.
• A4 data in pattern c accepts only 0, 1, or 2. However, the printer does not perform any data
integrity check. Therefore, a barcode will be printed even if any value other than 0 to 2 is
specified for A4 (P7) data.
