摘要： A printing bar arrangement for high-speed operation wherein the bars are slidably nested and supported in relation to one another and include tip portions capable of printing alpha-numeric characters upon precise striking of one or more of the separate bars. The printing bars are fixedly connected to blocks, also slidably nested, which blocks are positioned to be driven by appropriate solenoid mechanism wherein the coupling forces derived from an offset drive line are absorbed within the blocks to provide an even and parallel operation of the printing bars.
