How?
Before creating labels that print on a dot-matrix or tractor-feed printer, set the default printer and paper size.
In the Database window (Database window: The window that appears when you open an Access database or an Access project. It displays shortcuts for creating new database objects and opening existing objects.), click Reports .
If the resulting label report doesn't look the way you want, you can customize it in Design view (Design view: A window that shows the design of these database objects: tables, queries, forms, reports, macros, and data access pages. In Design view, you can create new database objects and modify the design of existing ones.).
If the printed labels don't look the way you want, customize the page settings in the Page Setup dialog box.
