Thermal printing mechanisms “Mercury” are multipurpose devices designed for use in various high-speed printing devices either stand-alone or built-in that can be used in different applications, for example in ECR, taxi meters, desk registers. Mechanisms contain casing with paper and thermal print head sensors, thermal print head and two-phase stepper motor for paper feed. Thermal printer mechanisms can be supplied with drivers (controllers) which implement all functions for controlling printer mechanisms and have interface for user device connection and command set. Till 2002 year we applied thermal print heads (TPH) of "ROHM" company in our all printer mechanisms that proved themselves as very reliable products. Since 2002 year we also started applying TPH of "SHEC" company that have increased effectiveness resulting in lower power consumption for printing and consequently more receipts printed without battery recharging.
