Direct thermal labels works by applying heat to the material. It does not use any ribbon, ink or toner, but it requires a special type of heat-sensitive material that blackens when heat is applied. As the label material is heat sensitive, it fades, and the label can become hard to read and scan over time. Direct thermal label rolls are good for short-term use.

Thermal transfer labels require a ribbon and use heat to create an image. Thermal roll labels use a thermal ribbon where heat from the printhead releases the ribbon attaching it to the label surface. These are very durable and longer lasting prints.
