Have you looked into System Preferences>energy saver>schedule? Maybe it's set up to start itself. I have my mother's mac set to start up and shut down automatically. Just a thought.  

Try "reinitializing" the device (printer):

1. Shut down the computer system the printer is connected to.
2. Unplug the printer power cord from both the printer and its power outlet.
3. Wait at least 5-10 minutes, then re-plug both ends back in.
4. Switch on the power button to the printer (if no indicator light is on).
5. Restart (reboot) system.

Also, you can also rule out it being a failed power outlet by trying a different one to plug the printer into.

Good luck, and please post back to let me know how things work out, or if you have any further questions.
