A method for use with an imaging apparatus that mounts a printhead having a plurality of ink jetting actuators formed on a substrate that correspond to a plurality of ink jetting nozzles includes determining a resistance associated with the printhead; accessing a memory having stored therein a plurality of individually selectable fire pulse energy values; selecting a first fire pulse energy value of the plurality of individually selectable fire pulse energy values based on the resistance that was determined; and using the first fire pulse energy value for actuating at least one of the plurality of ink jetting actuators during a printing operation.
