Your printer might appear offline if it can't communicate with your PC. Here are some things to try to get your printer back online.
- Check to make sure the printer is turned on and connected to the same Wi-Fi network as your PC. Your printer's built-in menu should show which network it's connected to, or check your printer's manual for more info.
- Verify that your printer is not in Use Printer Offline mode. Select Start > Settings > Devices > Printers & scanners. Then select your printer > Open queue. Under Printer, make sure Use Printer Offline is not selected.
- If these steps don't put your printer back online, then read Troubleshooting offline printer problems.
