A system for identifying workpieces by scanning them and "reading" details of their configuration is adapted for applying a desired pattern of material in powder form (e.g. toner material or a hot melt adhesive) to the workpieces regardless of their location and orientation on a workpiece support (18), using an electrostatic printer (36) e.g. an ionographic printer. This is achieved by pattern data (relating to the desired pattern) selected from a store being modified in accordance with positional data (relating to the location and orientation of the workpiece) obtained during scanning (Figure 2), such modified pattern data being utilised to apply the desired pattern of powder to the surface of the printing member (roller 38) of the printer such that, when the roller and workpiece are brought together the powder is applied in its pattern to the desired locality of the workpiece. |
