Abstract
A control for a dot matrix shuttle printer executing a sinusoidal velocity traversal across a line on a print medium comprises calculating the instantaneous position locations of the print elements during such traversal by making use of a lookup table. A dot image buffer stores information signals representing an entire line of desired dots to be printed. The calculated positions location information and the information signals are used to cause the desired dots to be printed in spatial sequence across a dot line at desired locations at the appropriate time during shuttle motion.
