Our laser foil materials, like the Gold Foil Laser (GF), typically work best in smaller, desktop laser printer models. When using a larger, commercial laser printer you'll likely need to print in smaller quantities to ensure that the sheets feed without jamming. If your printer has a material setting for "Labels" or "Transparencies" that should help with any feeding or toner fusion issues as well.
