Abstract (en)
The printing device comprises a printing head having a row of printing elements, e.g. 18 wires 31 actuated by corresponding electro-magnets for printing symbols and characters in conformity with dot matrices. The inclination of the row relative to the direction of movement of the printing is variable. With the row vertically aligned, the height 1 of the 18 wires is equal to that (h + b + h) of the two lines of printing 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 one line at a time with high definition dot matrices.
