Abstract
An electronic record storage system has plural stored changeable records including its content (e.g., a spreadsheet). Each record has a record identifier (e.g., its filename) which is not normally changed when the record content is changed. To facilitate synchronization of the stored and printed records, a version identifier (e.g., a timestamp) is changed when the content of that record is changed. The content of a such record includes marking from which the respective record identifier and version identifier are derived. A user scans the print marking to produce marking image data. A identifier and identifier are derived from the marking image data. The record identifier accesses the current record and obtains the currently-stored version identifier. The scan-derived version identifier is compared with the currently-stored version identifier. Version identifier timestamps need not be the record timestamp but can indicate printing time.
