We recently replaced our Pixma TR4257 Printer with the same, but a newer version.
It is connected and set up on our iMac.
It works with our iPhones, but for some reason, it won't recognize or communicate with my daughter's MacBook Air. It previously worked with her laptop before. The previous printer came up, and not our new one.
I finally was able to add the new one, but it won't print.
