Printer using ash

A device for airbrush printing a representation on a support, such as a sheet of printing paper, comprising a control panel, in which said representation is digitally stored, a platen of flat shape designed to accept the support, an airbrush printing tool designed for airbrush printing comprising a hopper and a reservoir designed to take ash and ink to be mixed by the hopper, the airbrush printing tool being designed to be able to create airbrush prints using the mixture contained in said reservoir and supplied by the hopper, the airbrush printing tool furthermore being mounted with the ability to move along three orthogonal axes relative to the platen and numerically controlled in its positions along said three axes by the control panel to allow the airbrush printing of the digital representation onto the support, in which the hopper is a dosing hopper designed to adjust the concentration of ash and of ink in the reservoir.
