Canon Printer Not Found on Mac? Connection and Offline Fixes

If your Mac cannot find your Canon printer or shows it as unavailable, the problem is usually related to the network connection, printer settings, print queue, or software configuration. A Canon Printer Offline on Mac can happen even when the printer is turned on and appears to be connected to WiFi.

If your Canon Printer Says Offline on Mac or you are dealing with a Canon Printer Not Connecting to Mac, work through the following troubleshooting steps before removing software or resetting the printer.

Why Is My Canon Printer Not Found on Mac?

Your Mac needs to communicate with the printer through WiFi, USB, or another supported connection. If that communication is interrupted, macOS may show the printer as offline or fail to detect it altogether.

Common causes include the Mac and printer being connected to different WiFi networks, a weak wireless signal, a changed WiFi password, a stuck print job, outdated printer software, or an old printer configuration stored on the Mac.

Check Your Canon Printer First

Before changing anything on your Mac, make sure the printer itself is ready.

Turn on the Canon printer and check its display or indicator lights. Resolve any paper jams, open covers, paper errors, or other warnings.

If you use wireless printing, confirm that the printer is still connected to your WiFi network. A printer that has lost its network connection will naturally appear unavailable to your Mac.

Make Sure the Mac and Printer Use the Same WiFi

This is one of the most important checks when a Canon Printer Not Connecting to Mac.

Your Mac and printer should generally be connected to the same local network for normal wireless discovery. If your router has a guest network, make sure one device isn't connected to the guest network while the other is on your main network.

If you recently changed your router, WiFi name, or password, reconnect the Canon printer using the new network information.

Restart the Printer, Mac and Router

Temporary communication problems can cause your printer to disappear from macOS.

Turn off the printer and restart your Mac. If you're using a wireless connection, restart the router as well.

Wait for the WiFi network to become fully available, turn the printer back on, and give it time to reconnect. Then check whether the printer appears on your Mac.

This simple process can often Fix Canon Printer Offline on Mac without requiring more advanced troubleshooting.

Check Printers & Scanners on Mac

Open System Settings on your Mac and select Printers & Scanners. Look for your Canon printer in the list.

If the printer appears, select it and check its status. If multiple entries exist for the same printer, make sure you're using the correct one.

An old printer entry may remain after changing your router or reinstalling the printer. This can sometimes result in documents being sent to a configuration that is no longer active.

Clear Stuck Print Jobs

A failed print job can prevent new documents from printing and may make the printer appear unresponsive.

Open the printer queue from your Mac's printer settings. Review pending documents and remove jobs that are stuck or showing errors.

Once the queue is clear, restart the printer and try printing a simple document.

If printing resumes, the problem may have been limited to a failed print job rather than the printer connection itself.

Remove and Add the Canon Printer Again

If your Canon Printer Says Offline on Mac even though the network connection appears correct, removing and re-adding the printer can refresh its configuration.

Open System Settings > Printers & Scanners, select the affected printer, and remove it.

Before adding it again, verify that the printer is turned on and connected to the correct network. Then choose the option to add a printer and wait for the Canon device to appear.

Select the appropriate printer and complete the setup.

Check the USB Connection

If you're using USB rather than WiFi, check the physical connection.

Disconnect and reconnect the USB cable. Try another compatible USB port or adapter if available.

Avoid using an unreliable hub while troubleshooting. Connecting the printer directly to the Mac or a known-good adapter can help determine whether the connection hardware is causing the problem.

If the printer works after changing the cable, port, or adapter, the original connection may have been responsible.

Check Canon Printer Software

Modern versions of macOS can automatically configure many printers, but some Canon models or advanced functions may require additional compatible software.

If the problem started after a macOS update, check whether your installed Canon software supports your current macOS version.

When additional software is required, obtain it through Canon's official support resources. Avoid unknown third-party driver download websites.

After updating or reinstalling the appropriate software, restart the Mac and test the printer again.

Canon Printer Offline on Mac but Connected to WiFi

Sometimes the printer reports a successful WiFi connection but macOS still considers it unavailable.

Try printing from another device connected to the same network. If another computer or phone can use the printer, the WiFi connection itself is probably working.

In that situation, focus on the Mac. Clear its print queue, remove outdated printer entries, and add the printer again.

Also check whether security software or network settings are interfering with local device discovery.

Canon Printer Not Found After Changing WiFi

Changing your router, network name, or password can break the printer's previous wireless configuration.

The printer may still be trying to connect using old network credentials.

Run the wireless setup again on your Canon printer and select your current WiFi network. Enter the new password carefully.

Once the printer reconnects, return to Printers & Scanners on your Mac. If necessary, remove the old printer entry and add the newly connected printer.

Check for macOS Updates

Keeping macOS updated can resolve compatibility and communication problems. However, printer issues can also occasionally appear after a major operating-system change when older software is no longer compatible.

Check for available macOS updates and review the software requirements for your exact Canon model.

Do not install random drivers simply because they mention your printer brand. Match the software to both the printer model and your macOS version.
