A magnetic paint ball gun firing apparatus provides magnetic coupling between rigid components that are used to position paint balls within a paint ball gun. In one embodiment, a device includes a substrate and a capacitor is formed on the substrate. If necessary, the status viewing station automatically transmits instructions, or a user enters instructions into the status viewing station, for instructing action be taken by the monitoring and control device or processor, e. In another embodiment, vertical blanking data of the data frame includes only consecutive horizontal lines of data. The printing system includes a first printer to print a first barcode on a medium including variable to be printed on the medium and a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium. In order to at least reduce the noise that is generated by the damper, the energy storing elements are connected to each other by at least one coupling device that is designed to ensure that, when one of the energy storing elements is deformed, there results a controlled entrainment of the other energy storing element or elements.
