SYSTEM AND METHOD FOR MANAGING ELECTRONIC PRICE LABEL OVERLAYS

摘要

A system and method of managing data for electronic price label overlays which automates printing of new and changed overlays. The method determines electronic price label information and price look-up file descriptions that have been added or changed for particular electronic price labels. Additions and changes in overlay data are marked and identified by the marks to create a print data file. Alternatively, additions and changes are identified by a comparison of a first file with a second file containing the additions and changes. The system includes a number of storage media for storing the PLU file and the EPL data file, and a computer which determines a change in the PLU file or the EPL data file and which creates the print file for printing an overlay for the change in the PLU file and EPL data file.
