With a card including a passive electronic paper display configured to display a visual image, a method of presenting information on a card includes selectively changing a visual image displayed on the passive electronic paper display to update information represented by the visual image, and wherein the card is sized to be carried by a user.
摘要:
An inkjet printhead, printing system and a method of inkjet printing employ a boundary layer control apparatus to control a boundary layer of air flow surrounding a nozzle opening of an inkjet pen. The printhead includes the pen supported by a housing that is configured so that the nozzle opening both faces a substrate and is spaced from the substrate by a gap. The apparatus is a structure adjacent to the nozzle opening and supported at a leading edge of the housing ahead of the nozzle opening relative to a direction of movement of the substrate. The structure is configured to extend into the gap. The printing system further includes the substrate. The method includes moving the substrate below the printhead, controlling the boundary layer, and depositing an ink onto the moving substrate.

Printers, methods, and apparatus to reduce aerosol are disclosed. An example apparatus to reduce aerosol includes a print head (102) to generate droplets (314-320) and aerosol (322-326), and to direct the droplets (314-320) toward a print substrate (104), a first corona wire (108) to generate first ions (340, 344) having a first electrical polarity to direct the aerosol (322-326) toward the print substrate (104), and a second corona wire (110) to generate second ions (340, 344) to direct the aerosol (322-326) toward the print substrate (104), wherein the second ions (340, 344) have a second electrical polarity that is opposite the first electrical polarity.
摘要:
An imaging device can include an imaging drum to support a carrier fluid. A roller can remove a portion of the carrier fluid from the imaging drum. A fluid container can collect the carrier fluid from the roller. A fluid remover on the container can be used to remove the carrier fluid from the roller.

A printing assembly includes a pressure control tank and a printhead assembly. The printhead assembly is in fluid communication with the pressure control tank while the printhead assembly and the pressure control tank are selectively rotatable into a plurality of different positions relative to one another.
摘要:
Apparatus to capture aerosols, fluid jetting apparatus, and aerosol diverters are disclosed. An example aerosol capture apparatus includes a corona wire to generate ions, and a reference plate positioned below the corona wire and above a substrate on which a fluid is to be deposited, the reference plate to provide a reference potential to direct the ions toward the reference plate to force aerosol particles associated with the fluid toward the reference plate.
