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.

Do not use with: Option Description

42	Price
60	Incrementing

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.
