For what?  Only the parallel port gives enough i/o from a PC with good enough control over the signal timing to drive steppers accurately.  The trend now is to remove parallel ports from new PCs so they have to use either Ethernet or USB but these don't give control over relative timing on multiple hardware channels so you need an external motion controller.
