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.

Abstract: A printer includes a print zone, a curing zone, first and second fans, a heat exchanger, a heat valve, and a fan controlling unit. The print zone includes a print head to lay down ink on a media. The curing zone treats the media. The first fan generates a primary flow through the curing zone to treat the media. The heat exchanger is downstream the curing zone on the primary flow to condensate vapors contained in the primary flow. The second fan generate as secondary flow through the heat exchanger to cool the primary flow. The secondary flow is able to reach the print zone. The heat valve releases the secondary flow into the environment, downstream the heat exchanger. The fan controlling unit controls the second fan taking into account an ink density of the ink laid down on the media and/or an aperture level of the heat valve.

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.
