Hi there and welcome
Has it been connected before to your wifi network? Or this is the first time you have tried?
Can you follow the steps on my link below to connect it to your wifi network again.
Once you have followed the steps, try to print and tell me please if it then prints.
The easiest method, if your router supports WPS, is to use that procedure.
Else you will need to use the standard connection method
Let me know please how you go Alan.
