UPC-E Expansion

The UPC-E symbology uses a special algorithm to suppress zeros in the

encoded data. The suppressed information can be restored by either the Omni

reader or the host system. If enabled, the reader will restore the data to its

original format. If the host system is set up to do the expansion, then this op-

tion should not be used.
