Claims

[Claims for Utility Model Registration] A printing head 1 having a platen 7, an ink ribbon 5 facing the platen 7, and the platen 7.
A printer comprising a print medium 6 that is transferred into a gap between the print head 1 and the print head 1, and a mechanism drive circuit 4 that controls the drive of the print head 1, and prints on the print medium 6 by the print head 1. The device stores a predetermined dot pattern P to be printed on the front surface and prints it on the print head 1 according to a front and back print command.
A first buffer memory unit 2 that sends out a front dot pattern P1 to the print head 1 that stores a predetermined dot pattern P to be printed on the back side;
an insertion/removal mechanism 8 for inserting and removing the ink ribbon 5 under the control of the mechanism drive circuit 4 during printing; and a sheet 9 having a transfer agent at a printing position on the back side.
