Fix the frustrating offline status error quickly with these proven diagnostic steps for Windows and Mac.
Confirm the printer is on, has paper, and shows no error lights or messages on its display. Check all cable connections if using a wired setup. For wireless printers, confirm the wireless indicator light is solid and not blinking.
Turn off the printer, then restart your router, then restart your computer. Once everything is back on, power the printer back on last. This clears temporary network glitches that cause most offline errors.
Go to Settings > Bluetooth & devices > Printers & scanners. Click on your printer, then click Set as default. Also click Open print queue and cancel any stuck jobs.
Open the print queue window. Click the Printer menu at the top. If Use Printer Offline is checked, click it to uncheck it. This setting sometimes activates automatically when a connection is briefly lost.
On Mac, go to System Settings > Printers & Scanners. Select the printer and click the minus button to remove it. Then click the plus button to add it again.
Print a network configuration page from the printer's menu. If the IP address starts with 169.254, the printer has not successfully obtained a network address — re-run the wireless setup.
If none of the above steps work, uninstall the printer from your computer completely, then download and reinstall the latest driver from the manufacturer's website.
