How to Print Photo Books, Calendars, Cards From macOS

Michael Potuck put together a list of five services to print photo books, calendars, cards, and more from your Mac with Photos extensions.
Even though Apple discontinued its printing services that were built-in to its Photos app, users don’t necessarily have to use a completely different app to get prints. Apple is supporting Photos extensions from third-parties to offer printing options.
Although it doesn’t have an extension that plugs into the Photos app, as a photo printing service I also recommend Artifact Uprising.
