Stimtracker, superlab and parallel port

We recently purchased an ASL eyetracker that requires that our stimulus program send event marker information over the parallel port. We found out too late that superlab does not support output over the parallel (lpt) port.

Before we switch to another stimulus presentation software, is it possible to use Stimtracker as a very expensive parallel port emulator with superlab 4.5 so we can continue to use Superlab for stimulus presentation.

A cursory examination of the superlab event options for Stimtracker doesn’t show me anything that would indicate that I can send event marker information from Superlab PC over USB to stimtracker and then from stimtracker over LPT to our eye tracker.
Am I mistaken?

It is indeed possible to send event markers over USB through StimTracker.
