A manually activated, value-metering system having a method and an apparatus for achieving synchronization, wherein the value metering system uses a digital print head to print a plurality of printed lines, one printed line at a time, on a substrate, which is advanced through a print zone of the print head in a moving direction. A mechanical restraint is used to restrict the movement of the substrate through the print zone such that the substrate is allowed to move a fixed distance after the print head has printed one printed line until the last is printed. The fixed distance is substantially equal to the width of one printed line.
