Abstract
The invention relates to a circuit arrangement for driving a plurality of printing jets in mosaic printers employing a plurality of tubular drive elements of polarized ceramic which hold printing liquid therein and whose diameter may be contracted or expanded by the application of suitably poled voltages thereto, in which activation of a jet takes place by the application of a pulse thereto comprising two half cycles of opposite polarity, the first cycle of which is operative to effect an expansion of the drive element from a normal rest condition, and the second is operative to effect a contraction of the drive element from its normal rest condition.
