I spent half a day in a hospital pharmacy testing our DS6878-HC scanner, right next to a Code Corp scanner. There are certain Symbologies Code Corp has on by default that we do not. Use the attached sheet to configure your DS6878-HC if you send this scanner out for any type of Healthcare demo. Alcon and Fera use a lot of RSS Limited Allegen and Akorn use RSS-14 Prasco uses Code 128 Johnson and Johnson is almost all RSS Limited Good luck.
