Providing an updated version of a printed document comprising storing data for generating an original version of a printed document, including a two-dimensional barcode that contains: data identifying the original version of the document, as well as at least a portion of the data for generating the original version of the document. The invention also enables the updating of the stored data so that a later version of the printed document may be generated including a new barcode for identifying and generating the later version. The barcode of a version of the document is scanned to determine if the scanned barcode identifies the later version of the document. If the barcode does not identify the later version, then the later version of the document is generated and printed. If the barcode does identify that the scanned document is the later version, the document is not printed and the user may be notified that the scanned version is the latest version.
