Improvements of the newer German version:
        o  Prints NEGATIVE NUMBERS in RED,
        o  Prints "real" negative results ( not complements! )
        o  Shows a RED FLAG as a "NEGATIVE SALDO WARNING"
           in a WINDOW  right over the [+]-Key
        o  Paper roll visible via an ACRYL COVER
