Thermal Label Printers
The tendency for the print location to alter slightly when printing longer runs on continuous labels adds the requirement for a sensor that detects the gap, notch, like or perforation between the labels, allowing the printer to adjust the intake feed. Thermal Label printers have a wide variety of applications, including supply chain management, retail price marking, shipping labels, blood and laboratory specimen marking, and fixed assets management. They are very common in any operation that uses barcodes to keep track of shipping, stock or equipment. There are two types of thermal printers: Direct Thermal - Uses heat sensitive paper (similar to fax paper). Direct thermal printing lasts 6 - 12 months before fading. If exposed to direct sunlight or chemical vapors, the label can have a much shorter life. Therefore, direct thermal labels are primarily used for short duration applications, such as shipping labels. Thermal Transfer - Uses heat to transfer ink from ribbon onto the label for a permanent print. Most thermal transfer printers are also capable of direct thermal printing. There are three grades of ribbon for use with a thermal transfer printers: Wax is the most popular with some smudge resistance, and is suitable for matte and semi-gloss paper labels. Wax / Resin is smudge resistant, suitable for semi-gloss paper and some synthetic labels Resin is scratch and chemical
resistant, suitable for coated synthetic labels For information on Thermal Paper and Thermal Printers, these pages may help:
