First, verify the printer is truly on your network and you're using the HP Smart app.
- Install HP Smart from 123.hp.com or your device's app store.
- Open the app and tap the Plus icon or 'Add Printer'.
- Select your printer from the list and follow the prompts to add it to your network. You'll need to create an HP account and register the printer.
IF THAT DIDN'T WORK: A third-party firewall or VPN on your device can block the connection. Disable them temporarily to test. Also, run the HP Print and Scan Doctor utility on a computer to diagnose and fix the issue automatically.
HEADS UP: The printer must be connected to the internet to use cloud-based print services. Check your router is on and the printer isn't too far from it.
