Abstract
A microprocessor (9) has output driver circuitry (20 FIG. 1; 30, 32 FIG. 2) which is selectable by signals on electrical lines (22 FIG. 1; 36 FIG. 2) to obtain different drive levels. In this manner mass produced microprocessors may be employed with output voltage selected to better match load and thereby reduce electrical noise from overshoot and ringing. Typically, each microprocessor when installed in a printer (1) or other apparatus will be selected to only one such status during the life of the apparatus.
