4. Operating Instructions
4.1 Dual Printing Modes
The OS-214plus Pro supports both Direct Thermal (DT) and Thermal Transfer (TT) printing. DT printing uses heat-sensitive paper and does not require a ribbon, ideal for short-term labels. TT printing uses a ribbon to transfer ink onto various label materials, providing more durable and long-lasting prints suitable for harsh environments or long-term storage.
