Canon Selphy CP400 under Windows 10

Back in the day, I bought a Canon Selphy CP400. Still have it! This is so long ago, I did not even remember the OS I was using to that time.
Now with my Windows 10 laptop, I wanted to revive the good old sublimation printer for use with Lightroom. Turns out, there are no drivers for Windows 10 available. Still I got the printer working perfectly fine. And this is how I did it.

1. Download the latest Windows Vista drivers.
2. Open the download folder and right-click on the downloaded file selecting "properties".
3. Click the "Compatibility"tab.
4. Click "Run this program in compatibility mode for:"
5. Select "Windows Vista"
6. Press Apply/OK

Double  click to install.
In the course of install you will be asked to connect the printer and power up. The installation should not finish.

The above procedure worked fine for me. Lightroom 5.7.1 on Windows 10 printed flawlessly on the old CP400.
