Some quick detail here. My form 2 which is connected to wifi only. 14 hour print, had around 4 hours to go at 10pm at night. I switched my wifi modem off (so kids cant watch movies in bed). I got up the next morning and my printer was frozen. I turned wifi back on but couldnt get it unfrozen. Im assuming the wifi is the problem as it hasnt happened before. I had to unplug the printer and ditch the print. What a waste.
