Abstract (en)
A device for direct electrostatic printing with an addressability AD in dots per cm, incorporating a printhead structure comprising a sheet of insulating material (106c) having a first and a second face, a number of printing elements (116), forming at least one row on said substrate. Each of said printing elements includes at least one printing aperture (107) through said insulating substrate. The printhead structure further comprises at least two sets of deflection electrodes and a voltage source coupled to the deflection electrodes for applying to each set of deflection electrodes a varying voltage with a frequency, f, correlated to the line time of the printing LT, so that f x LT > 1.00. Preferably the sets of deflection electrodes arranged so as to have at least two deflection electrodes from different sets near two adjacent printing elements. <IMAGE>
