Abstract
In a substantially continuous process, solid ink is melted and deposited on a recording roller where it solidifies as a surface coating. Subsequently, heat is applied selectively and locally to portions of the roller to remelt the ink. A recording chart pressed against the moving roller picks up and retains the melted ink, thereby dots or segments of characters are formed on the recording chart. A plurality of heating means may be used so that printing in a dot matrix is made feasible.
