Typically, matrix printers of the past have generated characters that are limited in the number of dots per character, since they were held in read-only storage (ROS). This meant that the machine was designed to print the stored images. In the current series of printers, the character images to be printed are not restricted to those with a small number of dots per character. This presents additional problems including power supply loading, ribbon loading due to increased forces from the actuators hitting the ribbon, paper and platen, and additional heating. The present system permits design for expected typical printing loads while allowing heavy dense characters with no adverse consequences.
