Press Command-S to save this Folder Action, and give it a name. Automator will save the Folder Action, attaching it to the selected folder. Now whenever you place a document in this folder, the document will print automatically.

You can check to make sure this works by right-clicking or Control-clicking on that folder and choosing Services -> Folder Actions Setup. (If you only have a few Services, you may not have a Services menu and will instead see the Folder Actions Setup menu item at the bottom of the contextual menu.) The dialog box that displays will show all the folders to which you have attached Folder Actions. When you click on a folder name, you’ll see the Folder Actions assigned to them.

If you select a different folder from the one you used above, then click on the plus-sign (+) button below the right-hand column of the Folder Actions Setup window, you will be able to apply the same folder action you created above to any other folders.

2. Automatically add Spotlight comments

Using Spotlight comments to tag files can help you find them more easily. I use Spotlight comments to add project names to files; when I search for a specific project, such as “MyLatestBook,” it’s easy to find all the files I need.
