Abstract
The needles (1) of this printer are fed by an electrical conductor (10) associated with the secondary of a step-down transformer (9) connected to a current pulse generator (8). The needle (1) having been placed in the magnetic field of a permanent magnet (7), the current (I) which passes through the needle gives rise to forces which tend to restore this needle to a straight line joining its points of support and guidance (2,3) while displacing the free end against a writing support.
