What is Direct Thermal

What is Thermal Transfer

Direct thermal printing uses heat-sensitive media that changes color as it passes under the print head of a direct thermal printer, which differs from industrial barcode printer models. Direct thermal printers are noted for their simplicity because they do not use ribbons. Direct thermal printing systems are not suitable for environments that are exposed to direct sunlight for extended periods or are subject to abrasion. For these reasons, thermal labels or ticket stock are often coated to protect against these elements. In thermal transfer printing systems, the printers are similar to a fax machine and use a ribbon, which is melted onto the label by the print head. They are also found in industrial barcode printer systems, and this method facilitates the use of label materials beyond paper, including synthetic materials such as polypropylene and polyester for harsh outdoor environments. Beyond the added durability, media printed with thermal transfer has a very long shelf life, making it an excellent choice for product labels, asset tags, and outdoor wristbands.

How Do Printers Connect to a Computer

As industrial barcode printers, each must be connected to some type of computer to receive printing instructions. While some printer models can be set up in a standalone mode, printers must first be connected to a computer to be set up. In addition to these, most printing applications require a fixed connectivity, so the printer knows exactly what to print.
