Note(s) This subclass covers: manually controlled power-operated apparatus or apparatus of this type with additional control by input of recorded information, e.g. on punched cards or tapes; the "print-out" features of apparatus controlled by record carriers or electric signals in so far as these are of general interest, e.g. impression, inking, line-spacing mechanisms, printing heads. [5] This subclass does not cover: electrical features of apparatus controlled by record carriers or electric signals and of interest apart from the "print-out" features of said apparatus; apparatus controlled by record carriers or electric signals, as a whole. [5] In this subclass, the following term is used with the meaning indicated: "paper" covers also similar flexible copy material; [3] "printing material" covers both paper and temporary record carriers from which records are transferred to a paper, but does not cover printing masters, e.g. formes.
