| 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.
