How Direct Thermal Labels Work
Direct thermal printers selectively heat coated label media. The image forms in the face stock, so no ink cartridge is required.
Before you buy: confirm your exact printer model, label dimensions and any brand-recognition requirements. DYMO states its LabelWriter 550 works exclusively with DYMO-branded labels.
The practical answer
Direct thermal printers selectively heat coated label media. The image forms in the face stock, so no ink cartridge is required.
What matters most
Match the printing method, label material and adhesive to the environment. For printer-specific behavior, use the manufacturer's current documentation rather than assuming all thermal systems work the same way.
Common mistake
Do not choose media from one attribute alone. Size, adhesive, face stock, printer support and expected label life interact.
Next step
If you use a DYMO LabelWriter, move from this concept guide to the printer-compatibility hub, then to the size or use-case page that matches your job.
