Abstract
A printer controller for supplying dot data to a printhead module having a plurality of nozzles for expelling ink, the printhead module including a plurality of thermal sensors, each of the thermal sensors being configured to respond to a temperature at or adjacent at least one of the nozzles, the printer controller being configured to modify operation of at least some of the nozzles in response to the temperature rising above a first threshold.
