The maximum firing frequency is 2400 Hz for alphanumeric printing and 2100 Hz
for graphic printing.
In the next figure are shown the typical waveform of the print head needle current.
The LOW and NORMAL energy can be selected via operator panel in order to
obtain the best performance in term of printout/noise when multiple forms paper is
used.
The timing values (
µ
sec) are programmed by the ASIC timer registers.
