Sourcebook data processing and printing system

摘要

The data processing and printing system allows newly acquired or updated data, e.g. provided by a hard disc, to be printed on the corresponding page of the sourcebook via a printer. Each of the sourcebook pages is provided with a corresponding printed barcode (4) when the page is first printed, which is scanned by a barcode reader within the printer to verify that the correct page is printed with the new or updated data.Pref. the active data is printed in black ink and the erased data is crossed out using a red line, for easy virtual identification of the active and erased data.
