1. Confirm the printer is really connected
Check the printer display or network report for its Wi-Fi or Ethernet status. Being powered on does not automatically mean the printer is reachable over the network.
2. Check the same network
Make sure the computer and printer are on the intended network. Guest Wi-Fi networks can isolate devices and prevent printing even when both devices have internet access.
3. Check the printer address
Find the printer's current IP address from its screen, app or network report. If Windows still points to an old address, the printer can appear offline even though it is connected.
4. Check the queue and print service
Clear stuck jobs, make sure 'Use Printer Offline' is not selected, and restart the Windows Print Spooler if the queue is frozen.
5. Re-add only when necessary
If the network path is healthy but Windows still cannot communicate with the printer, remove and add the printer again using the manufacturer's current setup method or its known IP address.
