Abstract: A printhead includes a moldable substrate, and a number of printhead dies molded into the moldable substrate. The printhead dies include a number of printhead dies molded into the moldable substrate. The dies comprise a non-rectangular shape. A number of fluid slots are defined in the moldable substrate to fluidically coupled to the printhead dies to feed fluid to the printhead dies. The number of fluid slots is not equal to the number of printhead dies.

Abstract: In some examples, a fluid dispensing device includes a fluid chamber, a heating element adjacent the fluid chamber, and an orifice adjacent the fluid chamber. A ratio of an area of a surface of the heating element to an orifice area of the orifice is greater than or equal to 3, where the surface of the heating element faces the fluid chamber.

Abstract: A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.

Abstract: A logic circuitry package includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit including at least one heater and a temperature sensor. The at least one logic circuit is configured to receive, via the interface, a heater command to address the at least one heater. The at least one logic circuit is configured to receive, via the interface, subsequent to the heater command, a sensor command corresponding to a sensor ID to address the temperature sensor. The at least one logic circuit is configured to transmit, via the interface, a digital value in response to the sensor command. The digital value corresponds to a print material level of a print material within a reservoir.

Abstract: A microfluidic system includes, in an example, a substrate and at least two microfluidic devices embedded into the substrate, at least one of the microfluidic devices being different from a remaining number of microfluidic devices. A microfluidic apparatus includes at least two microfluidic devices embedded into a substrate, at least a first microfluidic device of the microfluidic devices being heterogenous to at least a second microfluidic device of the microfluidic devices and a microfluidic channel to fluidically couple the microfluidic devices to each other.

Abstract: An example of an imaging medium includes an image-receiving substrate, a donor ribbon attached to the image-receiving substrate, and a registration mark. The donor ribbon includes a donor ribbon substrate, a release layer disposed on the donor ribbon substrate, and a color layer disposed on the release layer. The color layer includes a repeated pattern. A repeat of the pattern includes at least adjacent color stripes including a cyan stripe, a magenta stripe, and a yellow stripe, or a grid of four color sections including i) a colored section selected from the group consisting of black, cyan, light cyan, yellow, magenta, and light magenta, ii) a cyan section, iii) a magenta section, and iv) a yellow section. The color layer is in contact with the image-receiving substrate.

Abstract: The present disclosure is drawn to microfluidic devices. A microfluidic device can include a substrate, a lid mounted to the substrate, and a microchip mounted to the substrate. The lid mounted to the substrate can form a discrete microfluidic chamber between structures including an interior surface of the lid and a portion of the substrate. The lid can include an inlet and a vent positioned relative to one another to facilitate loading of fluid to the discrete microfluidic chamber via capillary action. A portion of the microchip can be positioned within the discrete microfluidic chamber.
