I connected my TS3122 by a usb cable, because wireless wouldn't work. However the printer still doesn't work. The installation disk didn't help either. I think it has a problem with windows 10. I'm still trying to figure it out.
I just bought the same model, PIXMA 31220, I've registered it and downloaded new drivers connected with usb cable and stll can't print with it. It must have problem with Windows 10. No answer for you but to wish you good luck.
