Abstract
A number of architectures of switch compensation networks are described for the provision of a compensation current which ensures the maintaining of a desired switching ratio in an acoustic printhead. The described architectures include those which provide column compensation, row compensation, and row and column compensation to a transducer switching matrix. Control of the switching ratio by the compensation networks, is used in consideration of the dissipation of heat energy through expulsion of a heated drop, to provide a precisely controlled balance.
