CheckNumberCalculation
The following barcode types must be given a check number for transfer to the printer:
Type H and I (EAN8)
Type K and L (EAN 13)
Type N and O (UPC A)
Type P and Q (UPC E)
The check number (c) is transferred after the barcode information (n). For the "EAN" type,
this is printed as the last figure in the HRI data line. For the "UPC" type, the check num-
ber is not printed in the HRI data line.
The commercial barcodes can be extended with the following user-specific additional bar-
codes (see also section "Add-On Barcodes"):
Add-On 2 barcode
Add-On 5 barcode
Here the check number (c) is transferred before the barcode information (n).
EAN 13 12 numbers are transferred for the EAN 13 code. The 13. digit represents the check num-
ber. The even figures of the information have a factor of "3", the uneven figures a factor of
"1". Counting begins from the left. The resulting cross sum is divided by 10. The remai-
ning figure is subtracted from the modul (10). If the remainder is "0", the check number is
also "0".
Example
Information 4012345678901
Factor 131313131313
Product 4+0+1+6+3+12+5+18+7+24+9+0
Cross sum 89
10 (modul) - 9 (remainder) = 1 (check number)
For remainder "0" the check number is also "0".
