I would love to see some of this. Brother is awesome because of how accessible the hardware and toner ecosystem is, but a lot of the older models are security hazards.

Unlike inkjet printers, laser printer controllers can actually cause some damage because of the high power fuser unit. Running the fuser continuously will melt the printer (or at least trip the hopefully hardwired thermal protection), and cycling it on and off rapidly can be unpleasant for other devices on the circuit due to the inrush current.
