Letters and numerals for increment/decrement
For CODE39 (standard), CODE39 (full ASCII), NW7, CODE93, and CODE128, if a data string other than numerals is included in the data, increment/decrement is performed. However, if any code which does not exist in each bar code table is contained in the data, increment/decrement is not performed.
Up to 40 digits (including letters, numerals and symbols) are possible. Only the numerals are picked up and calculated for incrementing/decrementing, and then are returned to the previous position to draw the data.
Example of increment/decrement calculation
Initial value | 00000 | A0A0A | 7A8/9 | A2A0A |
INC/DEC | +1 | +1 | +3 | |

2nd label | 00001 | A0A1A | 7A9/2 | A1A7A |
3rd label | 00002 | A0A2A | 7A9/5 | A1A4A |
4th label | 00003 | A0A3A | 7A9/8 | A1A1A |
5th label | 00004 | A0A4A | 8A0/1 | A0A8A |
Example of increment/decrement of data including the special codes of CODE128
Increment/decrement calculation starts from the last digit in the data strings. When the data string to be calculated is numeric, and the next (upper) digit is “>”, that is a special code (shown with underline below). The next digit is calculated without incrementing/decrementing these two digits.

The leading zero(s) in a data row is replaced by a space(s) according to the designated number of digits. However, if the number of digits to be suppressed is greater than the data row, the data row will be drawn without zero suppression. Where the data row exceeds the maximum number of digits (40), the data row will not be drawn.
When the print data including start/stop code is sent, the start/stop code is also counted as a digit. When the bar code type is JAN, EAN, UPC, or UCC/EAN 128, the data will be drawn without zero suppression.
