Abstract
A printing device comprising a printing head having 18 wires actuated by a corresponding number of control electro-magnets for writing on a recording support symbols and characters in conformity with dot matrices. The writing ends of the wires are aligned along a single line, the slanting of which relative to the direction of movement of the carriage is variable. With the writing ends vertically aligned the height of the 18 wires is equal to that of two lines of writing, as a result of which it is possible to print two rows of characters simultaneously. By inclining the head and suitably selecting the speed of movement it is possible to print a line at a time with high definition dot matrices.
