Abstract
A method of printing, including providing a fluid ejection device that includes a substrate, a plurality of drive units formed on the substrate, each drive unit including at least two drive elements electrically coupled in parallel, and a plurality of fluid ejection elements disposed on the substrate, each fluid ejection element of the plurality of fluid ejection elements electrically coupled with a single respective drive unit. Electrical power is selectively supplied via the plurality of drive units to the plurality of fluid ejection elements to cause fluid to be expelled from the fluid ejection device based on image data.

A method of printing, comprising:
- providing a fluid ejection device comprising:
- a substrate;
- a plurality of drive units formed on the substrate, each drive unit comprising at least two drive elements electrically coupled in parallel;
- and
- a plurality of fluid ejection elements disposed on the substrate;
- and
- selectively supplying electrical power via the plurality of drive units to the plurality of fluid ejection elements to cause fluid to be expelled from the fluid ejection device based on image data,
- wherein each of the plurality of drive units is electrically coupled with a corresponding single respective fluid ejection element.
