Abstract
A fluid ejection device includes a substrate, drop generators formed on the substrate at a high density, primitive select lines, and a ground line. The drop generators are arranged in primitives of drop generators. Each drop generator includes a heater resistor having a high resistance. Each primitive select line is separately electrically coupled to a corresponding one of the primitives and is configured to connect to a power source. The ground line is electrically coupled to all of the primitives.
