Abstract
In the thermal transfer printer for printing with an ink ribbon in plural columns, a center of a flat portion formed on the platen roller of a contact portion of the thermal head and a center of the thermal head are shifted corresponding to an amount of shift of printing position as against a center of width of the ink ribbon. When the printing position is set above as against the center of width of the ink ribbon, the center of the thermal head is set above width (P) of the flat portion being formed on the platen roller of the contact portion of the thermal head. When the printing position is set below as against the center of width of the ink ribbon, the center of the thermal head is set below width of the flat portion being formed on the platen roller of the contact portion of the thermal head. The present invention can prevent the shifting-up or the shifting-down of the ink ribbon at the thermal head in structure in which the center of the ink ribbon width and the center of the printing shift in the plural columns printing.
