Printer is on Wi-Fi, but it is on the guest network
Guest Wi-Fi is often kept separate from the normal home or office network. That can stop a computer or phone from finding a printer even though both devices say they are connected.
1. Compare the Wi-Fi names
Look at the Wi-Fi name on your computer or phone. Then look at the network name shown on the printer. Watch for words such as Guest, Visitor, or a separate guest network name.
2. If one device is on Guest Wi-Fi
If this is your own home network, connect the printer and the device you print from to the normal main Wi-Fi instead. Then try printing again.
3. If this is a workplace, hotel, apartment, school, or other managed network
Do not change network-security settings yourself. Guest networks may be intentionally separated. Ask whoever manages the network whether local printers are allowed.
4. If you must use a guest network
Some routers can allow guest devices to reach local devices, but that setting is router-specific and changes network privacy. Printer Triage does not recommend turning that on blindly. Use the router maker's instructions or ask the network owner.
