System and method for managing electronic price label overlays
First Claim
1. A system for managing EPL overlay data as the EPL overlay data changes during operation of an EPL system comprising:
- a number of storage media for storing a PLU file and an EPL data file; and
a store based computer which determines a change in the PLU file and the EPL data file in the EPL system, and which creates a print file for printing an overlay for the change in the PLU file and EPL data file, wherein the computer reads the EPL data file for a marked change and compares PLU descriptions in a PLU descriptions file to the PLU file to determine the change;
wherein the computer creates a master overlay data containing first data in the PLU file and the EPL data file, creates a temporary overlay data file containing second data in the PLU file and the EPL data file, and compares the master overlay data file to the temporary overlay data file to determine a third set of data representing the change.

Abstract
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.
