Abstract: A stand for supporting a printing device, the stand comprising: a first leg and a second leg, the legs having upper ends for vertically supporting a printing device to horizontally span the legs above a supporting surface; a crossbar fixed to the first leg at a first crossbar fixation point and fixed to the second leg at a second crossbar fixation point; and a linkage connected between the first and the second leg, the linkage comprising a first link, a second link and a third link connected in series, wherein: the first link is connected to the first leg in use at a first leg connection point; the second link is connected to the second leg in use at a second leg connection point; and the third link is connected to the crossbar to pivot about a third linkage pivot point and to the first and second links at first and second linkage connection points on opposite sides of the third linkage pivot point.

Abstract: A rendering apparatus, in an example, comprises a rendering zone disposed between a rendering material deposition head and a substrate, a processing module to process the rendering material, a heat exchanger to transfer heat from the processing module to air to be re-distributed to the rendering zone, a distribution system for re-distributing heated air to the rendering zone, a valve located between the heat exchanger and the rendering zone, a temperature sensor located in the rendering zone to detect a temperature of the heated air that is re-distributed to the rendering zone, and a control module to adjust a temperature of the rendering zone by controlling an aperture of the valve using a feedback signal received from the temperature sensor.

Abstract: A method for controlling a printer includes receiving a set of first variables for the printer, determining, using a machine-learning program, one or more second variables based on the set of first variables, and controlling a printer to perform a print job based on the set of first variables and the one or more second variables. The first and second variables may correspond to different types of printer settings. The machine-learning program may determine the second variables using a classifier model that may prevent partial curing or drying, print media deformation and/or other defects.
