Abstract
Digital micro-processor accessory for generating obliquely oriented character printing (cursive writing) under utilization of matrix print principles using a plurality of print elements (e.g. styli) arranged in one or more columns, as well as a character generator and a circuit for controlling the print elements, further including the following combination of elements; a plurality of differently long shift registers for operating in parallel; a data register receiving print character bits; a circuit for selecting column organized print information from the data register to be shifted through the shift registers in a first orientation such that a high point in a column receives the longest, and a low point, the shortest delay, and for inverting that order in response to a reversal in direction of printing; the shift rate determines the obliqueness; a data bit distributing circuit for selectively feeding the data bits having been shifted through the shift registers in the initial or the inverted order to the control circuits; and a circuit bypassing the shift registers for directly feeding the data from the data register to the print element control circuits for obtaining regular ver…
