Abstract
A dot matrix line printer includes a counter that counts a number of print actions performed by each of a plurality of print actuators. The accumulated number of print actions can be compared to a reference number of print actions representative of a useful print actuator life for each print actuator. The counting process is performed based on the horizontal dot density, the number of print actuators, the number of bytes of dot data that each of the actuators is required to process, etc. This structure and method enable maximized use of print actuators regardless of location along the actuator array.
