Nearly all stepper drivers deliver a constant current to the motor, or at least, it tries. While the nominal voltage needed for a stepper is essentially "irrelevant", setting the correct voltage determines the current available for the stepper, by the driver. This gets a little different to work out since the current is generally "clipped" or "chopped" as part of the function of the driver. (Ohms law is only really applicable to a stepper motor when it is not moving, btw.)
A minimum voltage is still required to overcome back-EMF.
Without going into the maths, your voltage settings determines your available current, basically.
