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

To assist you better, do you get any errors?

The printer can only be connected to 1 network at a time. You may connect it using a USB cable or wirelessly.

Click here to check the printer specifications. Also, the printer cannot be connected to a guest/university network.

Make sure the encryption method is WPA.

• 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.

Hope this helps! Keep me posted.
