EAN-13
EAN-13 is a fixed-length, numeric, continuous code that employs four element widths.
The printer supports EAN-13, which is a superset of UPC that encodes 12 digits.
Typically, the format starts with a number set digit, which defines how the next six digits
are encoded. The next five digits have fixed encoding. The last is a check digit. The
printer prints an EAN-13 bar code with the 12 digits sent to it and generates the check
digit. If fewer than 12 digits are sent, the remaining digits will be zeros. EAN 13 may
include an EAN 2 or EAN 5 Addenda.
