Appendix C: Bar codes
C-13
Example: bar code data 1234XYZg
Start in character set C, change to character set A.
a: Ref. Start character Set C = 105
b: Ref. character 12 = 12
c: Ref. character 34 = 34
d: Ref. change to Code A = 101
e: Ref. character X = 56
f: Ref. character Y = 57
g: Ref. character Z = 58
Calculation:
105+(1*12)+(2*34)+(3*101)+(4*56)+(5*57)+(6*58)=1345
1345 modulo 103 = 4 (1345 /103=13 Remainder 6)
Checksum is 6 (Reference value in Set A)
If you calculate this checksum yourself, you have to send the char-
acter HEX 26 to the printer in order to obtain the reference value 6
in Set A.
