ABSTRACT:
A method of activating a binary controllable element of a thermal head in correspondence with an N-bit data value representing a density value D by converting a digital signal representative of said N-bit value into a binary signal that, when applied to said transducer under control of a strobe signal, causes said physical value D to be generated.
The binary signal is composed so that it is active during a period t.sub.on, wherein t.sub.on on is equal to the sum of a number of time steps being selected from at least two different predefined time steps.
