A printhead structure for direct electrostatic printing having a back electrode and a particle supplying unit. The particle supplying unit conveys charged particles to a particle source positioned adjacent to the back electrode. A flexible control unit interposed between the back electrode and the particle supplying unit converts a stream of electronic signals, defining image information, into a pattern of electrostatic fields that within a predetermined print area of the print head structure selectively permit or restrict the transport of said charged particles from the particle source toward the back electrode. The flexible control unit is positioned and maintained in a spaced relation to the particle source. The flexible control unit is aligned with the particle source and the distance between a surface of the flexible control unit and the particle source is adjustable. Alignment edges are individually adjustable in a direction perpendicular to a surface of the flexible control unit, to increase or decrease the relative distance between the surface of the flexible control unit and the particle source.
