Abstract: According to an example, a computing device comprises a base portion and a lid portion rotatably coupled to the base portion. The lid portion comprises a platform, an aperture to receive the platform, and a flexible display panel disposed on the platform. Upon a deployment of the platform, an area of the flexible display panel on an upper side of lid portion is to increase such that the area overlaps with the base portion.

Abstract: An example three-dimensional (3D) printing kit includes a particulate build material, which includes from about 80 wt % to 100 wt % metal particles based on a total weight of the particulate build material. In some examples, the kit also includes a binder fluid, which includes water and a curable polyurethane adhesion promoter in an amount ranging from about 0.5 wt % to about 15 wt % based on a total weight of the binder fluid. The curable polyurethane adhesion promoter is formed from a polyisocyanate; an acrylate or methacrylate, the acrylate or methacrylate having at least one hydroxyl functional group and having an acrylate functional group or a methacrylate functional group; a carboxylic acid including one or two hydroxyl functional groups, an amount of the carboxylic acid ranging from 0 wt % to about 10 wt %; and a sulfonate or sulfonic acid having one or two hydroxyl functional groups or one or two amino functional groups.

Abstract: The present disclosure describes three-dimensional printing kits, methods of making three-dimensional printed objects, and three-dimensional printing systems. In one example, a three-dimensional printing kit can include a power bed material including thermoplastic polymer particles, a fusing agent to selectively apply to the powder bed material, and a post-processing agent to apply to a three-dimensional printed object. The fusing agent can include water and a radiation absorber that absorbs radiation and converts the radiation energy to heat. The post-processing agent can include a curable epoxy resin, where the epoxy resin, when cured, has a higher elastic modulus than the thermoplastic polymer particles.

Abstract: A fluid ejection controller interface includes input logic to receive control data packets and a first clock signal, each control data packet including a set of primitive data bits and a set of random bits, wherein the input logic identifies the random bits in the received control data packets to facilitate the creation of modified control data packets. The fluid ejection controller interface includes a clock signal generator to generate a second clock signal that is different than the first clock signal, and output logic to receive the modified control data packets, and output the modified control data packets to a fluid ejection controller of a fluid ejection device based on the second clock signal.

Abstract: An example electronic apparatus includes a communication unit, a user interface unit, a processor, and a memory. The processor is to execute instructions stored in the memory to receive, from the user interface unit, a request for an image forming operation on a document, obtain, by a first driver, a result of whether to approve the image forming operation, based on user information, from a server through the communication unit, when the image forming operation is approved, transmit, by the first driver, print data corresponding to the image forming operation to a second driver for the image forming operation, request, by the second driver, an image forming apparatus to perform the image forming operation, and, when the image forming operation is performed, transmit, by the first driver, history information corresponding to a result of the image forming operation to the server through the communication unit.

Abstract: Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.
