I just purchased a Canon pixma MG6220 and installed it last night. Both of my laptops can connect and print to it with no problems. I wanted to see how the scanner works, so I selected scan and then "forward scanned data to PC". After selecting this, I only get "local (USB)" as an option. If I tell it to search again for networked PCs, it does not find any and still only returns local (USB). FWIW, I do not have this printer connected at all via USB to any computer. How can I get my printer to locate my computers?
