This section describes the supported bar code types, and their usages and formats.

1D Bar Codes

UPC-A

The UPC-A bar code is the standard bar code format in the United States for items sold to

the public. UPC-A contains numeric data only, and encodes a 12 digit number. The first digit

is the system number character, the next five digits represent the supplier ID, the next five

digits represent the product number, and the last digit represents the required checksum

character. You do not need to specify the checksum digit, as the Bar Code Printing function

calculates it automatically.

One digit is represented by two bars and two spaces, and its width is calculated as seven thin

bars.

The system number character is printed as human readable text on the left side of the bar

code, and the checksum digit is printed as human readable text on the far right side of the

bar code.

The system number can have the following values:

0 or 7: Regular UPC codes

2: Random weighted items

3: The National Drug Code and National Health Related Items Code

4: For use without a code format restriction, and with a checksum digit for nonfood

items

5: For use on coupons

1, 6, 8, and 9: Reserved
