Generating Check Digits
You can make the printer generate a check digit. This option
is not necessary for UPC or EAN bar codes. The printer
automatically generates a check digit for these codes.
1. Define the text or bar code field
on the Format Worksheet, as
shown in Chapter 2, "Designing
a Format."
2. Find Option 31 on the Format
Worksheet. This option is for
check digits.
3. Write G in box R3, after 31. This tells the printer to
generate a check digit. The check digit will be the last digit
in the field.
4. Write the selector number of the check digit scheme (box
A2 above) in box R4.
NOTE: To allow for the check digit, the maximum number
of characters accepted in the field will be one
fewer than the maximum number in the field.
