Abstract

In a matrix printer, a hollow print needle 1 is connected to an ink storage tank through a flexible element (not shown) and, for printing, is accelerated towards paper 2 resting on platen 3. Upon impacting paper 2, needle 1 is decelerated, and inertial forces cause ink 4 to be ejected from needle 1 onto paper 2, generating a dot. The impact force of the print needle permits the simultaneous printing of multiple forms. The resolution is limited only by the needle geometry.
