Printer says offline or won't print

Steps

1. Turn the printer off, wait 30 seconds, turn it on. Wait until it stops making noises and shows its normal screen or steady light.
2. Restart the computer — properly, using Restart, not Shut down (Windows "Shut down" doesn't fully restart).
3. Check the printer is on the same Wi-Fi network as the computer. Most printers show the network name in their menu under Wi-Fi or Network settings. If you've recently changed modem or Wi-Fi password, the printer needs to be reconnected — use its Wi-Fi setup menu.
4. On the computer: Settings → Bluetooth & devices → Printers & scanners, click your printer, and if there's a queue of stuck documents open it and cancel all.
5. While there, click Set as default so Windows isn't sending jobs to an old printer or "Microsoft Print to PDF".
6. Try printing a test page from that same screen.

If that didn't work

• If it prints from your phone but not the computer, the printer is fine — remove it from Printers & scanners and add it again.
• If it stopped working right after a Windows update or a new modem, that's the cause; the reconnection above usually sorts it.
