Welcome to ask.fedora! It looks like your printer isn't properly installed yet. Go to http://127.0.0.1:631/, which is a way to use your browser to look at your printers. Up at the top, click on Printers. Ideally, you should see two: Cups-PDF and your printer. If you don't, click on Administration and Add New Printer. If all goes well, it will list your new printer, and you can add it. If not we'll worry about why not.
