Not with just a parallel port.
If you attach a Pico or Mesa card to the Parallel port, then maybe.

I took another look at the Y axis motor on my Acra, it's a MT30M4-59. (The 9
was hard to see.) I searched eBay and found this
http://www.ebay.com/itm/161076323614 with about 40 minutes to go. Snagged it
for $199.99, free shipping.
All the label data matches the motor on the mill
