The printer was working fine, and after upgrading my OS it doesn't print anymore.
I removed the printer and try adding it back, the OS sees the printer but was not able to add it due to "Unable to connect to ‘Canon MF260._ipps._tcp.local.’ due to an error. "
The scanner still works.
The MF260 app in my older OS doesn't show up anymore. I tried reinstall it and it didn't work.

Same issue, occurred after upgrading to Mac OS 14.3. Reinstallation, etc failed.

I had this issue and did a lot of research and testing of various things (including reinstalling, power-cycling, factory resetting, etc) and read on a forum that someone had fixed the issue by rebooting their Wifi/Internet router. I was skeptical, because that should really have nothing to do with my Mac connecting to my printer and everything else was working fine with the router, no issues...but believe it or not, it worked. As soon as I rebooted my FiOS 3100 router, my Mac immediately saw the printer that it had not been able to connect to for months. So as unlikely as it sounds, give it a try. Mine is a combined Wifi and internet router, but if you have separate devices, reboot them both.

Hello Ixh,
That message will usually come up when there is a network communication issue, or the incorrect driver is being used. You can make sure the MF Printer Driver & Utilities for Mac V10.11.12 has been installed. Once it has been reinstalled, you can try adding the printer back to the Mac. In the add printer window, you can highlight the printer and check the driver that is being selected in the "USE" drop down near the add button. It should have the name of the printer series.
If you are unable to select the printer series, you can try a restart of the Mac and you can try adding again. Since it is a network communication error, you can try power cycling your router, if you are getting the same message.
If you continue to have issues, I suggest contacting support over the phone at 1-800-652-2666. Our agents would be happy to help.
