Claim One:
1. A non-impact recording apparatus comprising a recording element; a current driver circuit that drives the recording element at one selected intensity of plural selectable intensities in response to a first signal that determines a single selected intensity for recording a pixel; a pulsewidth controller that controls the current driver circuit for a single selected pixel recording pulsewidth duration in response to a second signal that determines the single selected pulsewidth duration of plural selectable pulsewidth durations for recording the pixel and the single selected pulsewidth duration is the only pulsewidth duration used for recording that pixel; and a signal generator responsive to a multi-bit signal representing a grey level of a pixel to be recorded and generating in response to the multi-bit signal the first signal and the second signal, the signal generator selecting for a predetermined multi-bit signal one of plural selectable combinations of first signals and second signals to provide different combinations of first signals and second signals when recording different pixels of an image in response to multi-bit signals representing the same grey level; and wherein at least some of said different pixels that are recorded in response to multi-bit signals representing the same grey level are each recorded using a different one of said combinations of a single selected intensity of the recording element and a single selected pulsewidth duration.
