If the 'OPOS' option was selected in the Scanner field,
you must enter the OPOS driver name for the scanner here.
Both the Programmatic ID and the Logical Device Name can be used as the Device Name for the scanner
display. You can find the Programmatic ID and the Logical Device Name in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS\Scanner.
