Thermal Labels vs. Direct Thermal Labels
Direct Thermal Labels
- Does not require a ribbon – printer uses heat to make an impression
- If you have never replaced a ribbon, you probably use a direct thermal label
- Good for short term needs such as shipping or address labels
Thermal Transfer Labels
- Requires a ribbon to make an impression on label paper
- Good for long term needs, such as labeling, long term shelf storage, and labels subjected to more abrasive conditions
Label sizes are listed Width x Height. A 3″ x 2″ label has a width of 3″ and a height of 2″ when viewed from the front of the printer.
All printers have a maximum label width.
Outside Diameter and Core Size
The outside diameter and core (cardboard insert) size must match the specifications of the printer; typically, core sizes are 1″ (desktop), 3″ (tabletop) or ½” (mobile).
