Gecko power requirements

Okay, now I'm jazzed having the power supply built.

I *had* been planning on using another computer power supply
to deliver the 5 volts for the logic parts of the Geckos, but
noticed a mention of getting it from the parallel port of the
controlling computer in the Gecko white papers.

I'm a little unclear on the wording of it,
but it appears to me that I can eliminate
the secondary power supply and just use the
parallel port to get this voltage.

Am I getting this correctly?

If so, it would free up some space in my box.
