    Abstract: An example device includes at least one three-dimensional (3D) printed tablet and a 3D-printed production support structure. Each 3D-printed tablet includes an excipient material and an active ingredient. The 3D-printed support structure includes a 3D-printed planar structure comprising the excipient material and at least one 3D-printed connecting member comprising the excipient material. The planar structure includes at least one aperture, each aperture corresponding to one of the at least one 3D-printed tablet. The connecting member detachably connects the at least one 3D-printed tablet with the 3D-printed planar structure and positions the at least one 3D-printed tablets within the apertures.

    Abstract: In one example in accordance with the present disclosure, a method for assessing print quality is described. According to the method, a printed mark is converted into a digital binary mark. A number of values are calculated for the digital binary mark. The number of values include at least a perimeter length value and a value describing a characteristic of an intensity histogram for the digital binary mark. A combined representation of the number of values for the digital binary mark are compared against a combined representation of a number of values for a model printed mark. When the combined representation for the digital binary mark is greater than a predefined distance away from the combined representation for the model printed mark, an operation of a printing device that generated the printed mark is adjusted.

    Abstract: Examples associated with printer encryption are described. One example printer includes a data store to store a one-time pad. An encryption module may encrypt a message using the one-time pad. The encryption module also transmits the encrypted message to a trusted device that stores a copy of the one-time pad. A decryption module uses the one-time pad to decrypt a received message form the trusted device. The decryption module also controls the printer to perform an action based on the received message. A refresh module replaces the one-time pad during a service event.

    Abstract: According to examples, an apparatus may include a printhead assembly containing a housing supporting a printhead. The printhead may have nozzles that are to fire droplets of a functional agent onto a layer of build material particles along respective flight paths to form sections of a 3D object from the build material particles, an array of light emission devices to direct respective light beams in the respective flight paths, and an array of photon detectors to detect respective light beams directed from a light source of the array of light emission devices, the light emission devices and the photon detectors being supported on the housing. The apparatus may also include a controller to determine whether any of the nozzles is operating improperly based upon whether the photon detectors detected the light beams and to output an instruction regarding an improperly operating nozzle in response to a determination that the nozzle is operating improperly.
