Abstract
Disclosed herein is a thermoelectric printing method and apparatus pertaining to the technology which avoids the mechanical impact of printing elements upon an ink ribbon, as used in office machines or the like. In accordance with the method, an electrically insulating support of substantially two-dimensional perforated sheet material having two major surfaces, preferably glass fiber or nylon mesh material, is impregnated, in accordance with one embodiment, with electrically conductive printing ink, and, in accordance with another embodiment, with conductive ink in the form of pigment particles suspended in a dielectric binder. Then, by applying potential gradients or character signals across electrodes, sandwiching the support, one of which is permeable, ink is caused to transfer through the permeable electrode to paper or other recording material located outside the sandwich adjacent the permeable electrode.
