新型２４点阵低温热敏打印头以密排六角立方晶体结构（ｈｃｐ）的Ｔａ２Ｎ薄膜为发热电阻，增加了填充层，提高了传热效率。在－５～＋４５℃温度范围内，无论采用热敏打印纸、热敏蜡纸还是热敏色带，均可得到清晰的打印效果。印刷浓度的调节范围宽． The new 24-dot matrix low-temperature thermal printhead uses densely packed Ta2N film of hexagonal cubic crystal structure (hcp) as the heating resistor to increase the filling layer and improve the heat transfer efficiency. In the -5 ~ +45 ℃ temperature range, whether using thermal printing paper, thermal wax paper or thermal ribbon, can get a clear print. Printing a wide range of adjustment of concentration.
