Abstract
A method and apparatus for controlling power delivered from a power source to droplet sources in a printer is described. The described system uses a compensation value corresponding to each droplet source to compensate for differences between droplet sources. By using the compensation value to adjust the power delivered to each droplet source on a print head, a uniform droplet size is obtained from all droplet sources on the print head.
