The LTPH245 combines compact design, high-speed and high resolution thermal line dot printing with paper installation easier than ever before due to its mobile platen roller. By only pushing the release lever, the platen can be completely released and then firmly re-adjusted to evenly press the paper to the thermal head. The LTPH245 can be used with measuring instruments and analyzers, various POS applications as well as communication and data terminal devices. Furthermore, it is a maintenance-free mechanism which also features low-current consumption to support portable devices such as hand-held terminals.
