Free Label Templates | A4Labels.com - A4 Labels | A4 Label Sheets Always feed your labels in Portrait (narrow edge) as this is the direction of the grain (like wood) and ensures the strength of the label is retained. Laser and inkjet printers do not print right up to the edge of the A4 sheet, so if you have labels with no side border remember that you need to allow 3mm (depending on the printer) as a border.
