Hello!I'm on macOS Sierra 10.12.3 and I have last Canon driver installed (CUPS Ver.16.10.0.0 and ICA Ver.4.1.3). if I connect my PIXMA MG3550 via Network, it's not showed as a scanner But if I connect the printer via USB it is correctly showed as...
A little update...I hope it can help...If I add the printer using Bonjour protocol (I don’t know if your printer support it), “sometimes” macOS recognize printer and scanner functions.
