PROBLEM TO BE SOLVED: To provide a print head for high quality high speed printing. SOLUTION: In a print head 34 for printer, propellant flows through a channel toward a material 38 to be printed and a printing substance, e.g. ink or toner, is introduced into the propellant while being regulated and kinetic energy sufficient for reaching the material 38 to be printed is imparted to the printing substance. High speed high resolution printing is realized by means of a plurality of channels for directing the propellant and the printing substance. Before being introduced the channel and printed onto the material 38 to be printed, a plurality of printing substances are not mixed in the channel or registered again but mixed or superposed on the material 38 to be printed.
