For each totally black pixel of image data to be printed using a fluid-ejection printing device, it is determined whether the pixel is part of a line feature or an area fill feature of the image data. Where the pixel is part of a line feature, a first printing mask selected that is optimized for printing line features. Where the pixel is part of an area fill feature, a second printing mask is selected that is optimized for printing area fill features. Each mask specifies a number of fluid droplets to be printed and positions where the fluid droplets are to be printed. The selected mask is applied to the pixel. The pixel is printed using the mask that has been applied. The fluid-ejection printing device prints the pixel by ejecting the number of fluid droplets specified by the mask at the positions specified by the mask.

Selecting printing masks optimized for line features and area fill features of image data

A fluid-application mechanism is to cause fluid to be applied onto media. An electrowetting mechanism is to generate an electric field to affect the fluid applied onto the media.

Electrowetting mechanism for fluid-application device

A method of manufacturing a bioactive fluid dose on an ingestible sheet, comprising the steps of advancing the ingestible sheet to a dispense position, and activating a fluid ejector to dispense essentially a drop of a bioactive fluid onto the ingestible sheet.

Laminated ingestible dosage form for dispensing multiple bioactive substances

Various embodiments and methods relating to wiping of a print head are disclosed.

Print head wiping

A developer system component includes at least one surface configured to be driven so as to create fluid flow providing a shear force adjacent a cleaner.

Developer cleaning

A medicament ejector is provided which includes an ejection mechanism and a service mechanism. The ejection mechanism includes at least one ejection port configured to eject a medicament-containing fluid. The service mechanism is selectively deployable to service the at least one ejection port.

Medicament ejector with ejection port servicing

A light-filtering element for a display device is provided. The element includes at least one filter having a chamber with a filtering fluid, the filtering fluid selectively disposed in an optical path, and a liquid motion actuator selectively configured to move the filtering fluid substantially into and out of the optical path.

Color-generating device and display system

In one embodiment, a fluid ejection device is configured to receive a signal and ejecting fluid in response thereto, including an ink ejecting nozzle layer having a substrate with first and second surfaces joined along an edge, an insulating feature located on the first surface adjacent the edge and a flexible lead that bends around the edge and lies flush against the insulating feature.

Fluid ejection device with insulating feature

A filter for a display system is provided which includes a fluid chamber having a selectively moveable filtering fluid, plural electrodes being coupled with the fluid chamber to accommodate establishment of an electric field whereby the filtering fluid may be selectively positioned in an optical path.

Filter for display system

Method and dosage form for dispensing a bioactive substance

A mixing apparatus that includes a drop on demand fluid dispenser for adding an additive fluid to a receiver liquid to produce a composite liquid that includes the receiver liquid and the additive fluid.

Mixing apparatus

Filter for a display system

A projector that has a narrow-spectrum light source to complement a broad-spectrum light source is disclosed. The broad-spectrum light source has a broad spectrum. The narrow-spectrum light source has a narrow spectrum complementing the broad spectrum of the broad-spectrum light source.

Projector with narrow-spectrum light source to complement broad-spectrum light source

An imaging device includes an optical sensor carried by a print carriage. An optical guide has an input end in optical alignment with a maintenance item and has an output end in optical alignment with a location to which the optical sensor may be moved by the print carriage.
