Does your wife's computer have the same OS as yours - Win 8.1?
There is no printer driver available on the HP Support site for this model printer to work on Win 8.1 OS.
If you are able to print from the other computer, it means the printer hardware is working fine.
Is the printer wirelessly connected to your computer?
- Make sure the printer and the computer 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.
