APPARATUS AND METHOD FOR GENERATING DRIVE WAVEFORM, AND PRINTER

摘要

PROBLEM TO BE SOLVED: To prevent an overcurrent from flowing within a circuit caused by exceeding a boundary value of either the upper or lower limit set in a predetermined range for an accumulation result, thus leading to a sudden change in drive waveform when drive waveform data is accumulated in a process of the drive waveform generation. SOLUTION: A reverse protective circuit is provided between an adding apparatus 2 and a second latch. When the result accumulated in the adding apparatus exceeds the boundary value of either the upper limit or lower limit set in a predetermined range, it is corrected to the upper or lower limit value or a value close to either of the two.
