Printing With Thermal Printers in Cold Weather
Thermal printers are types of printers that print using carefully controlled heat generated by the print head. There are two types of thermal printers. Direct thermal and thermal transfer printers. Direct thermal printers, as their name implies prints directly on to the media. The media has a chemical coating that changes color with the heat of the print head. Thermal transfer printers use a ribbon that makes contact with the print head and the media. To create an image the heat from the print head is “Transferred” through the ribbon melting the ink in the pattern generated by the printer. The ribbon usually consists of a plastic lining that is coated ink on one side. Thermal transfer ribbons can come coated inside, or coated outside depending on the make and model of the printer the ribbon is used with. The ink is usually made of a wax and/ or resin. Wax ribbons are good for printing on natural paper media. Resin blended ribbons are usually reserved for printing on synthetic media that is very smooth. The higher the resin content the more smudge resistant the printed media will be. Since both of these printers rely on precise temperatures to create an image, both print technologies are affected by very cold conditions.
Direct thermal printers have an advantage when it comes to printing in cold conditions. Since the print head makes contact directly with the media, it can tolerate temperatures a little colder than thermal transfer printers can. Direct thermal printers … Continue Reading ...
