Claims (1)

[Scope of Claim for Utility Model Registration] Thermal transfer in which characters, figures, etc. are thermally transferred and printed by pressing a heating element constituting a printing head from one side of an ink ribbon coated with printing ink onto printing paper placed on the other side. In the type printer device, there is provided a means for detecting the amount of ink remaining in the print marks on the ink ribbon after thermal transfer, a current supply means for variably supplying a heating current to a heating element constituting a print head, and characters stored in advance.・Means for specifying print data to be printed from among print data such as figures, based on the actual remaining amount of ink detected by the remaining ink amount detection means and the print data specified by the specifying means; The amount of ink remaining when printing is done properly on the printing paper is predicted and compared, and if the actual amount of remaining ink is appropriate, heating current is supplied from the current supply means to the heating element as before, and the ink is A control unit that increases the current supply to the heating element to increase the print density if the remaining amount of ink is too large, and decreases the current supply to the heating element to lower the print density if the remaining ink amount is too low. A thermal transfer printer device comprising: and.
