Direct Thermal Printers
Direct thermal (DT) printers do not use ribbon, toner or ink, which makes it an economical printing option. Direct thermal printers can only print on heat-sensitive media, which blackens as it passes under the printhead.
Direct thermal printing is best for short-term barcode applications such as shipping labels, receipts, tickets and other indoor uses. Images may fade with exposure to heat and sunlight and are not designed to have a long lifespan.
