An inkjet printhead including: an elongate fluid manifold having a base comprising a plurality of fluid delivery compartments, each compartment having a fluid outlet and a bubble-venting cavity; and one or more printhead chips attached to the base, each printhead chip receiving printing fluid from one or more fluid outlets. Each fluid outlet is aligned with a respective printhead chip and each bubble-venting cavity is offset from the respective printhead chip.

An inkjet printing method includes directing a printhead of an inkjet printer towards a substrate to be printed, generating ink drops in the printhead of the inkjet printer, and directing the ink drops, after they have been discharged from the nozzle of the printhead, into a zone with a locally increased temperature in such a way that the volume of the drops is actively reduced during the phase of flight to the substrate.

Fluid ejection devices with particle tolerant thin-film extensions are disclosed. An example apparatus includes a printer; a reservoir; and a printhead including: a firing chamber; a channel to receive fluid from the reservoir, the channel is coupled to the firing chamber, the channel having an opening; and a particle-tolerant film disposed adjacent the opening of the channel, the particle-tolerant film disposed between the channel and the reservoir, the particle-tolerant film to deter particles within the fluid from settling in an area adjacent the opening.

An inkjet printhead includes: an elongate fluid manifold having a plurality of fluid outlets positioned longitudinally along a base of the fluid manifold; one or more printhead chips attached to the base of the fluid manifold, each printhead chip receiving printing fluid from one or more fluid outlets. Each fluid outlet is laterally flared towards a longitudinal edge of a respective printhead chip.

An inkjet printhead including: an elongate fluid manifold comprising: an inlet boss, an outlet boss, a longitudinal channel extending between the inlet and outlet bosses, a plurality of air cavities positioned above the longitudinal channel in a roof cavity of the fluid manifold, and plurality of fluid outlets defined in a floor of the longitudinal channel; and a plurality of printhead chips attached to the base of the fluid manifold, each printhead chip receiving printing fluid from one or more fluid outlets. The air cavities are defined by ribs extending from a roof of the fluid manifold towards the longitudinal channel and each rib has a lip protruding beyond a lower surface of the inlet and outlet bosses.

An inkjet printhead includes an elongate fluid manifold having a base which includes a truss structure. The truss structure has webs extending between opposite chords, wherein a plurality of openings between the webs and the chords define fluid outlets. One or more printhead chips are attached to the webs of the truss structure with each printhead chip receiving printing fluid from a plurality of the fluid outlets.

An inkjet printhead including: an elongate fluid manifold having a plurality of fluid outlets positioned longitudinally along a base of the fluid manifold, each neighboring pair of fluid outlets being separated by a support web; and a plurality of butting printhead chips arranged in a row and attached to the base of the fluid manifold, each printhead chip receiving a printing fluid from one or more fluid outlets. Each butting pair of printhead chips has respective butting end portions commonly supported by one of the support webs.

An inkjet printhead includes: an elongate fluid manifold having a base defining a plurality of fluid outlets; and a plurality of printhead chips attached to the base of the fluid manifold, each printhead chip receiving ink from one or more fluid outlets. Each fluid outlet extends transversely across the ink manifold and extends at least half a width of each printhead chip.

An inkjet printhead includes: an elongate fluid manifold comprising at least one longitudinally extending channel, the fluid manifold having a base defining a plurality of ink outlets, the fluid outlets being spaced apart longitudinally along a floor of the channel; a plurality of printhead chips bonded to the base of the fluid manifold, each printhead chip receiving ink from one or more fluid outlets; and a plurality of transverse ribs positioned across the channel, each transverse rib extending upwardly from the floor of the channel. One or more of the transverse ribs has a recess allowing fluid flow along the floor of the channel between the transverse ribs.
