Bit of update... I didn't get to work on the GPIO. However, I did just use a single relay module, power it off the Pi, and tapped the signal to the LEDs on my printer. I still use my switch to turn the fans on. However, when the printer sleeps, the fans shut off. I think it will be quite a while before I tackle the GPIO solution, if ever. Thought I'd share the idea.
