A power limiting circuit for controlling recording electrode energizing power in an electrographic recorder having a plurality of electrographic recording electrodes has a voltage and current monitor circuit for detecting the changes in voltage and current being supplied to electrographic recording electrodes. The monitor circuit is used to maintain the current and voltage levels at predetermined reference levels by inhibiting the firing of preselected ones of the recording electrodes in a first and a second inhibit mode of operation. In the first inhibit mode, the firing of the even numbered electrodes is inhibited to maintain the predetermined power levels being supplied to the recording electrodes. The inhibiting operation is extended in the second inhibit mode to inhibit the odd numbered electrodes as well as the even numbered electrodes in alternate recording lines for a further limiting of electrode energization power to the recording head.
