Thermal Printers

  • Thermal PrintersA thermal printer or sometimes called a direct thermal printer produces a printed image be selectively heating coated thermochromic paper, or thermal paper as it is more commonly known. The thermal print head itself is basically a row of heating elements that when a electrical current is supplied to the element it produces heat. When the paper passes over the thermal print head the coating turns black in the areas where it is heated, producing the desired image. Thermal printers produce excellent text, graphics and barcodes at very fast speeds. The only consumable for thermal printers is the paper roll. Care must be taken in selecting your paper roll grade; low cost papers tend to be very coarse and can act like sand paper on the print head drastically reducing the head life. Also, an industry myth is that thermal paper will lose its image over time, this may have been the case back in thermal printings early days however with the improvement in the paper technology, papers can now be stored for up to 25 years.
  • Impact PrintersDot Matrix or impact printers work in a similar way to the traditional typewriter, the print head runs back and forth along the page with the image being produced by the head impacting onto a ribbon to deposit ink onto the page. Each dot is produced by a tiny metal rod or pin being driven forward by the power of a tiny electromagnet or solenoid directly onto the ribbon. With the use of special pressure sensitive paper the ribbon can now be disposed of, as the pressure sensitive paper will act in the same way as carbon paper. Impact printers are generally a lot slower than their thermal cousins however they still have a part to play within the field of compact OEM printers.
