A printer comprising a printhead configured to selectively cause a mark to be created on a substrate, a first motor coupled to the printhead and arranged to vary the position of the printhead relative to a printing surface against which printing is carried out to thereby control the pressure exerted by the printhead on the printing surface, and a controller arranged to control the first motor. The controller is arranged to control the magnitude of current supplied to windings of the first motor so as to cause a predetermined pressure to be exerted by the printhead on the printing surface.

When a CPU of a printing apparatus generates a red energization pattern for causing a print medium to develop a color, the CPU generates a subtraction pattern obtained by subtracting a portion of an amount of energy from a magenta energization pattern. The CPU calculates a logical sum of a yellow energization pattern and the subtraction pattern, to generate the red energization pattern.
