ABSTRACT:
Matrix printer means having plurality of write heads. In order to be able to achieve a print width in matrix printer means that is greater than that of an individual write head and in order to simultaneously enhance the resolution beyond the basic resolution of the write head or in order to enable multi-color printing, a plurality of rows of write heads are provided. The neighboring write heads in one row and the rows themselves are arranged phase-shifted relative to one another or the colors of the write heads in every row and between the rows are cyclically interchanged. The plurality of required rows of write heads is thus reduced to a minimum.
