How to install Canon Selphy 760 on OS X 10.10 Yosemite

Canon does not seem to support this nice printer any more... Does anyone have any idea what driver to select, of what alternative there may be around. Or is this the end of a kind little photo printer? That would be such a waste of effort and production material. Any idea why a big company like Canon does not invest in updating its own drivers? Is that sustainable? Thanks for any suggestions... Best Hans
