There is a difference between hibernating and shutting down. You usually have to actually tell the computer to shut down or restart. It will hibernate on its own if it is set to do so, or if you close the screen on a laptop.My wife tried to print something yesterday. It wouldn't print. She gave up waiting on it. She took no action. Computer stays on. Everybody goes about their day. I log in later and do my stuff ... no printing. Computer gets shut down (not sleep/hibernate/whatever ... shut off). Computer gets turned on this morning. I go to print something and nothing happens. I tried deleting it from the que. ... You guys know the rest.
