The matrix printer with stationary head requires a smaller number of mechanical and electrical components than the standard matrix printer. By introducing the paper into the orifice provided for this purpose and by activating the detector, the paper is pressed between the two rollers. On the upper roller is located the pulse device which executes the recordings, displacing the paper. The process of printing on the paper begins at the moment when the paper is removed and lasts until the paper is removed completely. <IMAGE>
