<p>The invention relates to a control unit for a printing apparatus having a plurality of heat sources, each heat source being operatable at an individual power level, wherein the control unit is adapted to control the power supplied to the heat sources such that, at each instant, the sum of the delivered individual power levels is less than or equal to a maximum allowable power. The control unit is adapted to control the power delivered to the heat sources on the basis of sequential cycles and for each cycle, to receive for each heat source a requested power pulse duration, to schedule within said cycle instants at which power is to be delivered to the heat sources, based on the individual power levels and requested pulse durations and to deliver within said cycle the power according to the scheduled instants.</p> |
