My MX340 was printing fine from my 27" Mac with MacOS Sierra 10.12 - until I changed ink cartridges this time! I use aftermarket ones all the time with no problem. This time, it won't print! Yikes! It did print a 4 line paragraph and then when I tried to print a Word doc, it would not!!!! Oh, and the "solution" in the Canon troubleshooting section DID NOT WORK!!! I really like this printer and don't want to buy another one - plus, I'm now hesitant to buy another Canon if I can't get this one to work... had always used HP until this Canon - which I much prefer! Any suggestions?
