<p>PURPOSE:To apply an erasure energy optimum for energy at the time of printing to a thermal head by determining the erasure energy to be applied to the head based on applied energy data stored in memory means by determining means. CONSTITUTION:When a cancel key is depressed in a keyboard 14, content of a buffer pointer 3b is returned by one. If data in a buffer 3a indicated by the printer 3b is voltage switching code, voltage information is set, voltage data is obtained from a voltage switching table 2a based on the voltage information, and output to an output port 6. The output data is fed to a voltage switching circuit 7 to control a head power source 16. A voltage determined by this sequence is supplied from the source 16 to a head 12. A character code obtained from the buffer 3a is decomposed to dot information, and sequentially fed to a controller 8, a driver 9, and the head 12 to be erased.</p> |
