ABSTRACT:
An apparatus enhances the image in a high addressability printer by generating phase signals from a pulse width modulator and a programmable delay or buffer which are XORed with adjacent phase signals and combined with a corresponding data signal to form SET and RESET signals. The SET and RESET signals are used to form a phase and width modulated serial data signal.
