The printing machine is for printing in one or more colors and is formed with a color printing head forming a production system for a hole matrix (6). Toner formed as dry toner powder is transported from a container down to a document to be printed. The printing machine is equipped with a rotatable feeder brush, which receives toner from the container and feeds it onto a rotatable printing brush and further through holes in the hole matrix onto the paper to be printed. The hole matrix on its underside has an electrically conductive ring (8) around each hole connected to an integrated circuit (10). On the underside of the document to be printed is a support electrode connected to a voltage unit, the printing brush and the upper side of the hole m matrix. |
