Abstract
A printing-needles device to write on a registration support alphanumerical characters and graphic symbols according to a dots matrix in which the dots are printed by directly inking of writing ends of the needles without interposition of inked ribbon between needles and registration support. The ink is contained in a removably mounted cartridge and is carried by capillarity from cartridge to needles by means of cloth-fibres cable which has an end dipped into ink and the other end in contact with a side of needles. The needles have opposite side guided by a lateral wall perpendicular to terminal wall which guides the writing ends.
