I've been looking at Chinese laser cutters and have seen some as coming with LaserDRW and some with LaserCut. Both seem to be compatible with CorelDraw. Is there a difference between the two? And if so, exactly what is it? In particular, is the range of CorelDraw versions that work with LaserCut (11-X4 from what I can tell) different from those that work with LaserDRW?

Any help deciphering this mystery would be much appreciated.
