A method and printing system are provided for generation of a printed image, as is a data processing system for the conversion of printing data and a computer program for carrying out the method. On generation of a printed image, at least two adjacent raster blocks of image elements are illuminated with a light source. The surfaces of the raster blocks are charged dependent on the amount of incident light. On illuminating each raster surface, a portion of the light is also incident on the adjacent raster blocks. The photoconducting layer is charged in proportion to the total amount of incident light. The region colored with toner on the subsequent development of the photoconducting layer may be varied almost infinitely by varying the amount of incident light on the first and/or second raster surface, whereupon the line width of printed images is almost infinitely adjustable.
