Plain and simple answer is the VFD is throwing out a bucket load of electrical noise which is being picked up by the parallel port and also the stepper drives.
You need to try and contain that noise by having all wiring shielded and properly grounded (star point) You also may want to try filters on the VFD and also try and route your cables so that low and high voltages cables do not run together.
