This opens the “Services” window. It’s in the right panel. A context menu will appear. Now that the queue is stopped, you can clear the documents. Don’t close the Services window, as you’ll need it again in a few moments. Just click the search icon (or the search bar, if it’s permanently in your taskbar). A folder will appear. To do this, click a blank area inside the folder, then press Ctrl+A. This clears the print queue, and you can close this folder window. You can do this by clicking Services in the taskbar, or by pressing Alt+Tab ↹ until you get back to it.  The print queue should now be completely clear.
