Abstract
Bar code information is printed on a printable surface associated with a product, such as a label or container of the product, or the product itself, during a production run under the control of a printer computer. The bar code information may include two components of a composite bar code symbol, where the first component is either pre-printed or printed during a production run, and the second component is printed during the production run. The first component may identify a product that is carried in the containers, while the second component identifies a lot, batch, expiration date or commodity number. In another aspect, check data is used to confirm the accuracy of information that is used by a printer computer to control a printer. In another aspect, first and second bar code symbols portions are read to recover information, and a database is accessed to determine if the recovered information is consistent.
