Avery Multipurpose labels are compatible with all printers including copiers, and now come with NEW UltraGrip varnish technology! UltraGrip technology was designed to give you absolute confidence that you are putting only the highest quality product through your printers. The blue bar on the top, bottom and sides of the back sheet have varnish dots to ensure the printer feeds the label sheet correctly. Printers aren't perfect, so to ensure you get the best results, select 'labels' as the media type, and also use the multipurpose tray to load the sheets, as we always recommend when using our labels. The label format is 70 x 42.3 mm with 21 labels per sheet and are ideal for all sorts of applications.
