Hi Bruno,
I'm Paul and I'm here to help you with your concern.
Unfortunately, the most recent driver for Canon Pixma MP470 was for Windows 8.1 but you can install the driver in compatibility mode.
> Right-click on the driver installer, and click on Properties.
> Click the Compatibility tab.
> Check the Run this program in compatibility mode for the box and select the Preferred Windows.
> Click on Apply and click the OK button.
I hope this helps. Feel free to ask back any questions and keep me posted.
