![]() Direct thermal printers have no ink, toner, or ribbon. Direct thermal printed labels typically have a considerable shelf life but are not well suited for environments that expose them to heat, long periods of direct sunlight, or abrasion. Direct Thermal Printingīecause they print without a ribbon, direct thermal printers are noted for their simplicity. ![]() Each technology can produce one- and two-dimensional barcode symbologies, graphics and text at the same print resolutions and speeds. Thermal transfer printers are engineered to print within tight tolerances and to produce the exact bar widths that successful barcode printing and scanning require. Overall thermal label printers are ideal for barcode labels because they produce accurate, high-quality images with excellent edge definition. Direct thermal printing uses chemically treated, heat-sensitive media that blackens when it passes under the thermal printhead, while thermal transfer printing uses a heated ribbon to produce durable, long-lasting images on a wide variety of materials. Each method uses a thermal printhead that applies heat to the surface being marked. There are two thermal printing methods: direct thermal and thermal transfer. ![]()
