A scanner for scanning bar code labels and for providing data related thereto to a host computer includes a scanning apparatus for optically scanning bar code labels and for providing an electrical signal in response thereto, and a decoding circuit, responsive to the scanning apparatus for translating the electrical signal into a digital signal. A microprocessor, responsive to the decoding circuit, controls operation of the scanner and translates the digital signal into data to be provided to the associated host computer under control of control characters. The scanner further includes a non-volatile random access control memory in which control characters are stored, and an interface, connected to the host computer and to the microprocessor, for transferring data from the microprocessor to the host computer and for transferring control characters from the host computer to non-volatile random access control memory via the microprocessor.
