Hi there and welcome
Have you tried to connect the printer to the new wireless network?
If so, what happens when you do?
No problem, you can do this by following my instructions on my link below
This will then connect it to the new wireless network and will allow you to print to it again
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know please how you go
