ABSTRACT:
A date printing device, such as a postal meter, includes an electronic calendar clock which generates and stores signals representing different days and months of the year. The electronic calendar clock provides one input to a comparison circuit. Another input to the comparison circuit is provided by an encoder which generates signals representing the current setting of the date printing device. The comparison circuit samples inputs from the calendar clock and the encoder and generates a control signal when a mismatch is detected.
