I have recently changed Wifi at home and need to disconnect my Deskjet3720 printer from the exixting Wifi and re connect to the new one. How do I do that? I attach a picture of the only control panel on the printer

I wish I could help you.  I went through a whole complicated (way too complicated) process and managed to get the new wi-fi and router entered.  The wireless network test results congratulated me on the "successful setup" and showed the new network name and IP address, but the printer still doesn't print.   I wish I can remember how I got as far as I did to let you know but I am  a tech-ignoramus and alas, can only give you moral support and wish you success.
