We have a Canon MX490WS wireless printer connected wirelessly to a network with two computers. One computer is a desktop, Windows 7 Home Premium, connected to the router by cable. The other is a laptop, Dell XPS13, Windows 10, connected wirelessly.

The printer prints fine from the desktop, but displays as offline from the laptop. We get a popup when printing on the laptop, and it shows status offline in Control Panel. Shows "Printer: ready" on desktop Control Panel.

I turned the printer off and then back on and it did not resolve the problem.
Turned the router off and then back on and did not resolve the problem.
Turned everything off, then turned on router, computers, and printer, did not resolve the problem.
Went to uninstall and reinstall the printer in laptop Control Panel, but clicking on "Remove this device" produces no result.

Suggestions?
