Abstract
A printing apparatus for printing on a transfer medium using an ink medium with a thermoplastic magnetic ink. A thermal head selectively heats and melts the magnetic ink. A magnetic head urges the melted magnetic ink from the ink medium to the transfer medium. Both the thermal head and the magnetic head are positioned on the same side of the transfer medium. The distance between the magnetic head and the platen can be adjusted depending upon the thickness of the transfer medium to maintain a constant speed of ink transfer from the ink medium to the transfer medium. Methods of printing by ejecting the ink from the ink medium onto the transfer paper and for adjusting the distance between the magnetic head and platen to adapt to varying thicknesses of transfer medium are presented.
