Robot drawing on wall

I would like to build robot drawing on wall or wall plotter. I want to if anyone has build one that could share with me. I have iduino and was not sure it it will work or not. I was thinking to get this stepping motor driver from this

I wasn't sure if this strong enough to do the job. Also I would like to use g code or cad then download on arduino to draw on it. Can some give idea on this?
