PURPOSE:To exactly grasp all necessary performances including durability by using a system in which printing speeds in automatic aging actions are selectively set up in plural stages as needed. CONSTITUTION:MPU13 incorporated with input port, output port, and ROM is connected with RAM17 to temporarily store variable data on letter codes to be printed. The input port is connected with each one end of switches SW1, SW2, and SW3. SW1 receives printing startup command for automatic continuous printing actions, and SW2 selectively sets up the printing speeds to max. speed or usual speed during the automatic continuous printing operation. SW3 stops continuous automatic printing operations after the elapse of a fixed time period or selectively sets up whether the operation is continued until the power source is interrupted. Since the printing speeds can be selectively set up to two kinds, max. speed and usual speed, as needed, the printing speeds can be selected according to measuring characteristics, and all necessary performances including durability can be exactly grasped. |
