[Supplementary Explanation] 
1. This command supports UPC-A only. When barcode type is specified other than “H”, command error occurs. 
2. Recommended to specify [02] or [03] for the narrow bar width. 
3. Check digit (12th digit) for HRI data should be set the calculation result of modulus 10. 
4. Setting of Guard bar, HRI and Ratio is following. 
 
5. When the parameter value exceeds the range, operation is not supported. 
6. HRI will not be printed when barcode is error for barcode with HRI. 
 
7. All character barcode have the same height when printing UPC-A specifying <D> and then <font>. The first and the last 
character barcode have the same height to the guard bar when printing UPC-A specifying <BL> and then <font>. 
When printing UPC-A specifying <D> and <font>, HRI can be printed under the first digit and the last digit because the height of the 
first digit and the last digit of the barcode is low.    When printing UPC-A specifying <BL> and <font>, the height of the first digit 
and the last digit of the barcode is high, and the font interval is narrower than previous case.
