    Abstract: A method includes printing, by one or more printer heads of the printing system, a reactive layer onto print media. The method also includes printing, by the one or more printer heads, a determined number of transmission layers and a determined number of barrier layers in alternation with one another. At least a portion of the reactive layer is configured to migrate through the transmission layers. The method further includes printing, by the one or more printer heads, a reactant layer that is configured to change color responsive to a reaction that occurs between the reactant layer and the reactive layer upon migration of the reactive layer through the determined number of transmission layers. The reaction is configured to occur on a received expiration date.

    Abstract: A marker transport system and a method of operating the marker transport system can include one or more print heads and a marker transport platen upon which a sheet of media moves. The transport platen can include airflow sections comprising process-direction slots. The plates can move in a cross-process direction, and can control airflow in an area under the print heads. The one or more plates in a first position can allow for airflow when the sheet of media is located at the first position and in a second position can block the airflow at the second position. A vacuum can be provided under the sheet of media as the sheet of media traverses a print path across the marker transport platen. A no-vacuum inter-document zone can be provided, which moves along with the sheet of media under the one or more print heads.

    Abstract: An inkjet printer is configured with capping stations for storing printheads in the printer during periods of printer inactivity so the viscosity of the ink in the nozzles of the inkjets of the printheads does not increase significantly. Each capping station has a printhead receptacle with an opening corresponding to a perimeter of a printhead, a pair of members pivotably mounted to the printhead receptacle so the members can move between a first position where the members expose the opening of the printhead receptacle and a second position where the members cover the opening of the printhead receptacle, and an actuator operatively connected to the pair of members to move the members between the first position and the second position. A controller is operatively connected to the actuator to operate the first actuator to move the members between the first position and the second position.

    Abstract: A printer system includes a memory, a processor, and one or more printer heads. The processor determines a number of transmission layers and a number of barrier layers to use in a color changing expiration indicator based at least in part on a time period between a print date of the indicator and a received expiration date. The printer heads print a reactive layer onto print media, where at least a portion of the reactive layer is configured to migrate through the transmission layers. The printer heads also print the determined number of transmission layers and the determined number of barrier layers in alternation. The printer heads print a reactant layer that is configured to change color responsive to a reaction between the reactant layer and the reactive layer upon migration of the reactive layer through the transmission layers. The reaction is configured to occur on the received expiration date.

    Abstract: Printer structures include a controller, a marking engine operatively (meaning directly or indirectly) connected to the controller, and a container connected to the marking engine. The marking engine applies marking material to print media, and the container stores that marking material. The container can include a flexible bladder storing the marking material, and an actuator structure operatively connected to the controller. The actuator structure contacts the flexible bladder and periodically moves portions of the bladder to periodically mix the marking material as controlled by the controller (based on the marking engine being idle for a previously established amount of time). Alternatively, the actuator structure contacts the container can periodically rotate the container to periodically mix the marking material as controlled by the controller.
