I just changed routers and now the printer won't print from my laptop or cell phone and it won't scan.

@Hairshan, Welcome to the HP Support Community! I’m here to help.

As you have a new router, the wireless settings on the printer have to be updated.

On the printer screen, go to Setup > Network Setup > Restore network settings

Go back to Network > Wireless > Wireless setup wizard and select your network.

• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

• This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK

Perform a ping test to check the connectivity

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
3. Enter “ping” followed by the IP address of the printer. 
4. Press Return. Press ctrl C after 10 pings
5. There should be 0% packet loss, share the results in your next post.

Hope this helps! Let me know how it goes.
