How do I reset (cold start) Laser Jet P2035n ?

I was able to search down the answer (on the HP support web site).

To reset to factory settings a P3025n printer:

1. power it down
2. hold down BOTH buttons (go and cancel)
3. power on (still holding down buttons)
4. all lights come on at same time, success
5. power cycle again and it'll get a new IP on 192.168.168.xxx
