Thermal printing process for such as cash registers uses remote wire less link to identification unit to provide automatic adjustment

摘要

The thermal printer has a print head [11] in a housing [2] that has a compartment for the installation of a thermo sensitive print roll [3]. On the side of the housing is a radio frequency receiver [7] and this connects remotely to a radio frequency identification memory chip. This provides automatic adjustment when a new paper roll is installed.
