The network that the printer operates on no longer exists

[David-H-M]

My deskjet 4155e printer was installed on a network that no longer exists. How do I change its network to the one used in the house

Hi @David-H-M,

Welcome to the HP Support Community. 

I'd be happy to help you! 

What network you are referring to?

Is it a private (Home network) or a public Wi-Fi connection? Wi-Fi direct? Or Hotspot?

Have you made any changes to your router network or software?

Make sure, your printer and your device are on the same network as 2.4GHZ only. 

Let's restore the Printer's network settings for the connection issue:

Press and hold the Wireless button ( ) and the Cancel button ( ) from the printer control panel together for three seconds.

Once done, try connecting the Printer to the Wi-fi.

Let me know if this helps.
