If this is a standard Labels layout, you can browse the layout in list view and see a single column of your labels records. If you enter preview mode, you'll see the grid of labels as specified for the layout when you set it up.
With label layouts, it's often useful to use a script that selects the layout and then enters preview mode and pauses. While paused the user can confirm that they have the correct records in their found set for the labels and can go put label stock in the printer. They can even flip though the pages of the preview to figure out how many pages are needed. Then they can select print from the FileMenu. When done they continue the script by clicking the continue button or pressing the enter key on the numeric key pad.
