Hey there - I encountered an issue awhile ago where no data would emit from the parallel port because the control register in the pport that dictates whether it’s sending or receiving information was flipped. Check out my post [here](https://discourse.psychopy.org/t/issue-reading-parallel-port-pin-for-button-box/9759). Hope that somehow helps! Good luck!
