For a description of the thermal printer and its operation, see an article on the EPN2100 thermal printer in the Artifacts Historical File. The EPN2100 was a version of the printer used in the Canon Pocketronic Calculator and was similar to the EPN2300 in this assortment. The principles of construction and operation described in the article apply to the printheads in this assortment. Thermal paper was known at the time of this development, but a small, efficient thermal printer that operated on battery power had never been produced.
