Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
You have to connect the printer to your new WiFi network and then add it back to your computer.
There are mainly two ways to connect the printer to your WiFi network. One is by connecting to the WiFi on the printer itself and the other is by using your computer/tablet or phone to setup Wireless on your printer.
Let's try first method.
Turn on the Printer.
In the Home screen,click the Setup button.
Select Device Settings
Select LAN Settings (if you see Wireless LAN Setup on home screen, then select it)
Select Wireless LAN Setup > Standard Setup. This will find your WiFI network. Select it and enter the password ***** your WiFi network. This will connect the printer to your WiFi network.
Now you need to connect the printer to your computer. To do that, on your computer, press Windows and R keys on computer and this will bring Run. Type control printers and press enter. From the resulting screen, click Add Printer or on your computer from Start > Control Panel > Device and Printers > Add Printer
