Abstract
To enable an impact printer, employing a daisy wheel print element and a ribbon which is raised to an up or print position from a down or character viewing position, to print without loss of portions of the characters because of incomplete ribbon lift caused by contact between the ribbon and the print wheel, provision is made for enhancement of ribbon lift by controlling the direction of print wheel rotation during ribbon lift.
