In order to avoid stepper motor overheat, it is strongly advised to respect the maximum
ON/OFF duty cycle as indicated above. Note that the maximum period for the ON time is 30
seconds (when the duty cycle is not 100%).
Example : at 7 volts, the duty cycle must be less than 30%. So the maximum ticket length at the
maximum speed is 30s at 72mm/s so 2.16 meters. Then the printer must rest for 70/30*45s = 70
seconds.

How to optimize speed consumption and maximum peak
current
The printing speed is always a compromise between 3 parameters :
Paper feed speed (function of voltage)
Head activation time (function of voltage)
Maximum peak current available (function of voltage and maximum number of dots
simultaneously activated)
For a given voltage, and a maximum current available, it is easy to determine the maximum
paper feed speed (MaxPFS), as indicated on the above chart. Then if the two others parameters
are not limiting this speed this will also be the printing speed (MaxPS).
