How to install Canon printer with Big Sur

Go to system preferences -> security and privacy -> firewall tab -> firewall options -> a kind of rectangle it says file sharing smb on top -> you click the + bottom left side of the rectangle -> then look for both:

/Applications/Canon Utilities/IJ Scan Utility/Canon IJ Scan Utility2

and

/Library/Image Capture/Devices/Canon IJScanner 13f

you have to click the + twice for each 2 application 1 at a time

that should do and you will be able to scan.

Best of luck

I recently installed Big Sur and removed all software not compatible with this macOS, including Canon Printer software, including all 'canon' files from the User Library (Prefs '.canon.plist', Plugins 'CIJAutoSetupTool.app', Caches, Extensions, Library-LaunchDaemons 'jp.co.canon.MasterInstaller.plist', etc).

Downloaded the Canon software 'mcpd-mac-mg5700-16_40_1_0-ea21_3.dmg' - successfully installed 'Printer Driver MG5700 series' compatible with Mac Big Sur.

I had no other printer drivers installed, so as instructions, tried to 'Add' the latest driver while the Canon Printer was plugged in and switched on - nothing doing. Printer could not be found.

Before the upgrade from High Sierra to Big Sur, this Canon inkjet printer was working without a problem. The Printer software was obviously compatible and a fairly recent upgrade (whilst being used with High Sierra) was successfully installed.

I used to have no problem sharing this printer and printing files sent from my older iMac running MacOS El Capitan. I will now try adding a driver compatible with MacOS El Capitan to see if it will work with the older iMac.

malayap .... this worked and I was able to install driver (I have Canon MX700), but I can't add printer. It doesn't show up in printers list. I did right click and reset, but nothing happened. Any suggestions?

After I following your advice I can definitively say it doesn't help. No drivers for my canon printers appear.

I don't see any available drivers at Canon's website for Big Sur, so not sure what others are working with.

Also, Gutenprint which I have used for decades to support many printers appears to be stale and lists no support for Big Sur either?

Would have thought Apple would include these drivers with the OS? They did with High Sierra.

Maybe Apple got a payoff from Canon to force us all to buy new gear.? Just Kidding. I hope.

Thank for the Gutenprint tip. Although it says that it is compatible only until 10.14 and it has problems with Catalina it works flawlessly on my M1 Pro MacBook Pro and Monterey with a Canon PIXMA iP4200.

If you have a Canon printer with wireless functionality - I have the MP560 - and there are no printer drivers available on the Canon support page for that printer, try looking at the "Apps & Function" tab on the same page. The Canon smartphone app can be used to print documents from your phone, with the catch that the docs have to be in a supported cloud server, e.g. Dropbox or GoogleDocs. It would be helpful if under the tab on the Canon support page that says no drivers are available if it would point you to the app.

Found this great website with a variety of drivers depending on the software you are currently running on your device. Found the MP270 once for Big Sur towards the bottom of the list. Hope this helps!

Please follow the advice noted above!

In the meantime you might try this workaround: the free, open-source Gutenprint print driver. Check this page to see if your printer is supported: Gutenprint Supported Printers  

Hi MrRMP,

The exact Canon printer model would help.

Also see About AirPrint - Apple Support.

No dice, unfortunately. Booted into Safe Mode, attempted the reinstall with the same result. Looks like this is something that Canon will have to resolve.

Driver no longer works. I have asked them if they have plans to fix it. If I have no satisfactory reply by 1 January I will have to go and by a non Canon printer.

Is the installer a package like this:

If it is try using Pacifist  to install the drivers.

What advice? I cannot even install the driver. There is an issue with running the installer.

Please read the whole thread, the advice is the 2nd post.
