Abstract: A drop ejector array device includes a first plurality and a second plurality of drop ejectors that are alternatingly disposed along an array direction on the substrate surface. A voltage input terminal and a current return terminal are disposed on the substrate surface. A first power bus line connects the first plurality to the voltage input terminal. A second power bus line connects the second plurality to the voltage input terminal. The second power bus line is electrically connected to the first power bus line by a primary power bus connector line. A first current return bus line connects the first plurality to the current return terminal. A second current return bus line connects the second plurality to the current return terminal. The second current return bus line is electrically connected to the first current return bus line by a primary current return bus connector line.
