I thought i'd share my long time idea about having printer completely go off when print is done. Too bad there is no such thing as CODE to make printer go off, power supply will stay on all the time. So i ended up buying Stanley 110v timer cheapest i could find was $11 on amazon or ebay. I hooked it up the way shown in the pictures and came up with fairly good result. I had to drill bigger hole for the reset button to make it easier to press so i can simply set the time off without having to worry about current time being correct, i just set the hrs and minutes printing software estimated + few more minutes and go to work. I hope this will inspire you to do a better one.
