Abstract: LINE ADJUSTMENT APPARATUS FOR A TYPEWRITER Line end adjustment decisions for a typewriter printing from text storage are based on a set of zones that are defined along the line respective of appearance considerations for the right margin. The potential end location for each successive word ready for addition to a line is calculated and such end location is compared to the previous word's end location, by reference to the appearance zones, for determining whether or not the word should be assigned to the next line (i.e., whether or not a carrier return is inserted). By so identifying the word end positions that bracket a word with respective corresponding zones, decision logic, based on preferred responses to the various zone combinations presentable by such end points, is enabled, effectively, to impose an overall pattern of preferred line ending decisions to establish a right margin. For a preferred implementation, the line ending decisions for one or more of the zone combinations are further influenced by the position of the end point of the previous line, which consideration is important to the visual impression produced by the succeeding line ending point.
