Checksum calculation for the symbol Cat
Data C <CTRL> + A <CTRL> + T "C" "K"
Data Values 12 46 10 46 29
C Weights543 2 1
K Weights654 3 21
1) For "C", sum the products of the (C WEIGHTS * DATA VALUES).
(1 * 29) + (2 * 46) + (3 * 10) + (4 * 46) + (5 * 12) = 395
2) Divide 395 by 47.
395 / 47 = 8 remainder 19.
Therefore, the value of "C" is 19, which corresponds to character J.
3) For "K", sum the products of the (K WEIGHTS * DATA VALUES), starting with the newly
calculated "C" digit.
(1*19) + (2*29) + (3*46) + (4*10) + (5*46) + (6*12) = 557
4) Divide 557 by 47.
611 / 47 = 11 remainder 40
5) The value of “K” therefore is 40, corresponding to character /. Send to the printer:
