摘要

A printer for transferring images onto recording paper (302) comprises
   a platen roller (303) having a circumferential surface to which said recording paper (302) may be releasably clamped and wound for the printing of images;
   a driving means (306) for rotatably driving said platen roller (303) in a rotational direction, said direction of rotation defining at least an output position and a printing position;
   a thermal printing head (305) disposed at said printing position and being moveable between a first position wherein said head is in operational contact with said circumferential surface for transferring images onto said recording paper (302) clamped to said surface and for applying a pressure force to said paper, and a second position wherein said head is out of contact with said surface;
   a discharge means (313) disposed at said output position for discharging said recording paper (302) following completion of the transfer of images thereto; and
   an ink sheet (314) moveably disposed between said circumferential surface and said thermal printing head (305), said ink sheet (314) comprising at least a first area containing an ink and being operative for transfer of said ink to said paper by said printing head (305) and a second area operative to permit contact by said head for applying a pressure force to facilitate movement of said paper to said discharge means (313) without transfer of color.
