A liquid drop ejector is provided. The ejector includes a liquid chamber and a liquid supply. Portions of the liquid chamber define a nozzle bore. A liquid supply passageway is positioned between the liquid chamber and the liquid supply. The liquid supply passageway is in fluid communication with the liquid chamber and the liquid supply. A plurality of pillars is suspended in the liquid supply passageway. A wall of the liquid chamber can extend to the liquid supply passageway. A center pillar can also be included with a portion of the center pillar being positioned in the liquid chamber and another portion of the center pillar being positioned in the liquid supply passageway.

Liquid ejector having internal filters

Both an inkjet printer and method are provided for controlling inkjet printing on a receiver. The inkjet printer includes a printhead having at least one nozzle for ejecting a stream of ink droplets, a droplet deflector for generating a flow of gas that impinges on the stream of ejected droplets to deflect the trajectories of the droplets, and a controller for varying the velocity of the gas flow in order to vary the degree of trajectory deflection so the droplets intended to print on a particular pixel in the receiver land on top of one another without elongation despite relative movement between the printhead and the receiver. The printer provides improved image quality and productivity while reducing image artifacts.
