    • 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.
    • 电子记录存储系统具有包含其内容(例如,电子表格)的多个存储的可变记录。 每个记录具有记录标识符(例如,其文件名),当记录内容被改变时,其不被正常地改变。 为了便于存储和打印的记录的同步,当该记录的内容被改变时,版本标识符(例如,时间戳)被改变。 这样的记录的内容包括从其导出相应的记录标识符和版本标识符的标记。 用户扫描打印标记以产生标记图像数据。 从标记图像数据导出标识符和标识符。 记录标识符访问当前记录并获取当前存储的版本标识符。 将扫描导出的版本标识符与当前存储的版本标识符进行比较。 版本标识符时间戳不需要是记录时间戳,而是可以指示打印时间。
