Unfortunately, this printer is very limited use: it does not work under Windows!
I have both the supplied, as well as the latest driver tried, however, both after a long installation forever denied the service. I tested this on Windows 7 (64-bit) and Windows 8 (64-bit). When I called the Canon Support and described the problem, I was told that there are no circumstances at the moment for the Selphy CP810 and Selphy CP900 the functioning Windows drivers, since the absence of a digital signature. One could not say when functioning driver will be available to me also. I was only asked to give regularly to the Canon Support site for new drivers out.
After that I tried to print photos via an SD card. However, the printer told me that on the map No images were available, even though I have these saved in * .JPG format and the directory tree of a digital camera.
The only way for me for me to print photos with this printer was wlan with my Android smartphone in combination with the Canon-App.
The photo quality was then, as expected, but the way to printed photo but not the how imagines him.
The described circumstances mean for me that the printer can make back on the road again - the 14-day Return Policy goodness!
