Direct thermal and thermal transfer are two common types of label printers used for printing barcodes, labels, and other variable data on various materials. Both types of printers use heat to transfer ink onto the label, but the process of ink transfer differs between them.
- Direct Thermal Printers: Direct thermal printers use a heat-sensitive paper or label material that darkens when exposed to heat, eliminating the need for ink, toner, or ribbons. These printers use a print head that generates heat and applies it directly to the label material, producing a high-quality, long-lasting image.
Direct thermal printers are typically less expensive than thermal transfer printers because they do not require additional consumables such as ink or ribbons. However, the print quality and durability of direct thermal labels may vary depending on the label material used, as they can be affected by heat, light, and moisture.
- Thermal Transfer Printers: Thermal transfer printers use a ribbon made of wax, resin, or a combination of both to transfer the ink onto the label material. The printer heats the ribbon and presses it against the label material, melting the ink and transferring it onto the label surface. Thermal transfer printers can print on a variety of materials including paper, synthetic, and polyester labels.
The advantage of thermal transfer printers is that they produce high-quality, long-lasting images that are resistant to heat, light, and moisture. Additionally, thermal transfer printers can print on a wider range of materials than direct thermal printers. However, they require additional consumables such as ribbons, which can increase the cost of printing.
In summary, direct thermal printers are a good choice for applications where the labels will not be exposed to harsh environments, and where cost is a primary concern. Thermal transfer printers are better suited for applications where label durability and print quality are critical, and where a wider variety of label materials need to be used.
There are many DT and TT printers available in the market, and the most popular models can vary depending on the specific industry, application, and requirements. However, here are some direct thermal and thermal transfer printers.
