Abstract
The line-wise printing of an image composed of an assembly of image elements (pixels) by means of a printing head which includes a row of N (N.gtoreq.2) printing elements which are arranged along an image line at a mutual distance from each other. The printing stroke is greater than the distance between two neighboring printing elements so that there is created at least one strip in the image in which there are pixel positions which are covered by m (2.ltoreq.m.ltoreq.N) printing heads. For this strip (or strips) several options are then presented for printing the pixels situated within them. A pixel in such a strip can now be printed by one or by several of the m printing elements, the allocation of one or more of these m printing elements to a position being capable of being chosen as fixed or variable. Furthermore, it is possible, if a pixel can be printed by several printing elements, to distribute the pixel printing values of the relevant pixel point over these several printing elements according to a fixed or variable distribution code.
