Abstract
To enable an automatic typewriter or the like equipped with a hammer-type impact printer to print substantially straight and uniformly dense underscoring lines, provision is made for automatically forming multiple character underscores from a series of overlapping underscore characters. Moreover, to optimize the appearance of the underscoring, provision is made for automatically centering single or multiple character underscores relative to the character or characters which are to be underscored.
