B41J2/05 - CPC Classification

Classification description:

Typewriters or selective printing mechanisms characterised by the printing or marking process for which they are designed characterised by bringing liquid or particles selectively into contact with a printing material; Ink jet characterised by the jet generation process generating single droplets or particles on demand by pressure, e.g. electromechanical transducers produced by the application of heat
