Abstract
Control circuit for a print head of a metal paper printer in which electrodes are arranged on a slope, said electrodes being staggered in horizontal projection by the D-fold of their electrode width. The martrix-like structurized character to be printed consists of individual image elements stored in a main storage. This character information is read out column-by-column and written into predetermined locations of a read/write buffer storage. The write phase is followed by a readout phase of predetermined locations of the buffer storage for the direct addressing of the electrodes of the writing head. Write and read phases alternate. For determining the address of the storage locations during the write and read phases two counters are used in connection with a multiplier and an adder as well as a register for storing the D-value.
