where is the Printer control panel on Deskjet 2800 all in one series printers

I have 2 issues:

1. I want to turn OFF Wifi direct on a Deskjet 2800 all in one series printer.  The model # is 2855e. This printer does not have a button to turn it off.  

2. Where and how do I access the Deskjet 2855e control panel to access settings for this printer.

Turning OFF wi-fi automatically turns OFF wi-fi direct.
