An Easydriver can only supply a max of 750mA whereas your motor requires 2000mA.
You might get away with using a Pololu DRV8825 with a heatsink and maybe a cooling fan. However if it was my project I would like a stepper driver that could handle 3 or 4 amps - and they are a lot more expensive.
Note that the rated voltage is essentially irrelevant. The important thing is the motor current.
