A performance monitor determines a performance characteristic of a plurality of dispensers receiving fluid from a reservoir. Each of the plurality of dispensers has an actuator that, when actuated, causes the each of the dispensers to generate a droplet of the fluid. A driver generates a drive command to the actuator to adjust a physical attribute of the droplet based on the performance characteristic to satisfy a performance criteria.
