Abstract

Disclosed is a controller that addresses problems involved with high resolution image signals when the frequency of data presentation to each actuator element of a printhead is higher than the maximum frequency with which the actuator elements can be effectively actuated. This problem arises when, for example, the sheet speed is so high that data must be presented to the printhead at a rate higher than normal. The disclosed controller is also useful in situations when it is desired to print at a lower than normal resolution (i.e., image resolution), for example, when printing a draft of a letter, while using enough of the image data to preserve high resolution curved or diagonal lines.
