Video: Printer does not need ink

Inkless printers designed by Dutch scientists will greatly reduce printing costs and do not adversely affect the environment.

Non-ink printing technology saves costs and reduces bad impact on the environment.

Scientists from Delft University of Technology, Netherlands, invented a type of inkless printer , according to Science Nature Page. This new technology is based on the "carbonization" process when focusing a laser beam to burn the surface of a sheet of paper.

By precisely controlling the beam width, laser energy and combustion time, the burned points turn black in the pre-programmed position, forming characters or drawings as printed. ordinary printer. Scientists expect this inkless printing technology will soon be applied to save costs and reduce adverse environmental impacts.
