Environmentally acceptable metal chlorides and, if appropriate, fillers are mixed with the ash in a first step and the resulting mixture is subjected to agglomeration andor compaction or conversion into particles. The extraction electrode defines an extraction aperture therein and the extraction electrode is positioned such that the extraction aperture is disposed proximate the tip of the ionization needle. High-frequency electric power of 13. The printing system also includes a second accessory device coupled to receive printed pages from the first accessory device.
