Abstract
Abstract A vacuum fluorescent printing device is disclosed having cathode filaments, a plurality of multiplexed control grids and a skewed matrix of addressable phosphor elements configured on a fiber optic plate in such a fashion as to enable light emitted from the phosphor elements to be directed edgewise through the fiber optic plate to expose a photosensitive member.
