Abstract: PURPOSE:To make an operator of a printer know easily that the printer is put under restriction by providing a detecting means that detects that the printing speed becomes lower than a specified value, and an indicator that informs the operator of the detected result. CONSTITUTION:Sheet-feeding signals inputted from a printing section 2 is received with a detecting section 3 that detects the fall of the printing speed, and the detecting section 3 converts the received signals into printing speed equivalence. The converted result is then compared with a preset boundary value for detecting the fall of the printing speed and are outputted as detecting signals 3a that detect the lowering of the printing speed. An indicator 5, mounted on an operation panel 4 for indication of the fall of the printing speed, receives the detecting signals 3a and indicates the state of the printing speed for informing the operator of the same.
