ABSTRACT:
The thermal printer system is comprised of a means for generating heated air and a means for controlling the application of the heated air to a thermally sensitive recording medium. In an embodyment of the invention there is provided a means for ionizing a column of gas and a means for attracting or repelling the ionized column of gas along a desired path in response to a control signal. Interposed along the desired path is a means for heating the gas and a thermally sensitive recording medium positioned to intercept the column of heated gas such that a record is made on the recording medium which record is a function of the control signal.
