| 摘要 |
A thermal printer for transferring ink from an ink film to a printing medium is described. The thermal transfer printer includes a print head and a platen. The print head has a plurality of resistance heating elements operable to be individually energized with electrical drive pulses. Each of the resistance heating elements has a transfer surface which is substantially flat for transfer of the ink from the ink film to the printing medium. The print head is pressed against the platen during printing. At least one of the transfer surfaces includes a concave portion which substantially avoids the transfer of the ink.
