ABSTRACT:
An electrodynamic printing system with at least one conductive stylus electrode against the back side of a sheet to be written upon and a store of solid conductive writing material, preferably in a roller electrode form, disposed on the opposite side of the sheet. A circuit is provided to apply current pulses between the electrodes causing current flow therebetween through the sheet sufficient to erode writing material from the front electrode and cause it to become implanted on the sheet, for forming a writing pattern. A linear array of stylii aligned with the roller provides a line printer apparatus.
