I was looking for this solution too for someone else. Apparently Canon does not support this like HP does. Google Could Print was a solution, but they quit offering that after 2020. A VPN would be the next thing I would try. You need a router at home...
Thank you so much for that! My saves were taking 25 seconds. Logging in as a secondary user made it instantaneous. I am only editing JPG files, not RAW. I was not looking forward to learning new software.
