Abstract
A curvilinear, semi-rigid paper guide for a bi-directional line printer mounted on a platen which provides a surface that bears against the moving print head as the print medium passes between the print head and the paper guide is disclosed. By adjusting the curvature of the paper guide, differences in the distances between adjacent drive sprockets of upper and lower print medium drive mechanisms may be compensated for thus ensuring the printing of straight, parallel and unskewed character lines. In addition, the present invention may be used in a line printer having a single print medium drive mechanism to compensate for nonlinearities in and non-parallelism between the surface of the platen and print head movement.
