In a given organization, thousands of pages of material are printed only to be read once and discarded. We are developing a desktop printer and reusable paper substrate capable of producing a high-quality, high-contrast image, which may subsequently be erased and rewritten multiple times without any expendable materials, such as toner or chemicals. Current related investigations include the development of color substrates and the development of electronically addressable, extremely high-resolution color wall-coverings, public message boards, whiteboards, and art canvases.
