Exact questions
Common questions about “Canon printer says offline in Windows”
Is the Canon's status shown on its screen?+
Check the printer's display for a network or error message. If it shows a Wi-Fi symbol that is off or flashing, reconnect it to the network from the printer's own setup menu.
Why does Canon show offline?+
Windows may have lost the printer port.
Is Use Printer Offline ticked?+
Untick it.
Should I re-add the printer?+
Remove it and add it again.
Does the port match the IP?+
Check the port in printer properties.
Should I reset the print spooler?+
Restarting the Print Spooler service clears stuck jobs that keep a printer showing offline. Open Services, restart it and try again.
Is the printer set as default?+
A different default printer can confuse where jobs go. Choose the Canon and print again.
Does the Canon software help?+
The Canon printing app or utility can help reconnect the printer to Wi-Fi. Use it to run the setup again, and confirm that the printer's network name matches your router.
Could an old Canon port be selected?+
Windows may still point to an old port after the router changes the printer's address. In printer properties, check the port and update it to the current IP address of the printer.
