Abstract: In some examples, a fluid dispensing assembly removably mountable in a fluid dispensing system includes a body and a fluidic die attached to the body. A vent is arranged on the body to direct cooling airflow generated by an external airflow generator that is external of and separate from the fluid dispensing assembly into an inner portion of the fluid dispensing assembly, the inner portion being within the body.

Abstract: A fluid ejection system may include a first fluid ejection module and a second fluid ejection module. The first fluid ejection module may include a first end, a first module face and a first row of first ejection heads having first ejection faces along the first module face. The second fluid ejection module may include a second end opposite the first end, a second module face and second ejection heads having second ejection faces along the second module face. The first module face and the second module face are spaced by an inter-module mesoscale gap.

Abstract: A fluid ejection device may include a laminate fluid manifold including plates in a laminate plate stack. The stack may include a fluid passage extending to an edge of the laminate plate stack. A die maybe secured across the edge of the laminate plate stack, wherein the die includes opening to receive fluid transmitted through the fluid passage.

Abstract: A fluid ejection device may include a laminate fluid manifold comprising plates extending in a plane and stacked in a laminate plate stack. The stack may include a first fluid passage extending parallel to and between plates of the laminate plate stack and a second fluid passage extending parallel to and between plates of the laminate plate stack. The first fluid passage and the second fluid passage overlap when viewed from a direction perpendicular to the plane.
