An electrothermal recorder comprising a thermosensitive recording surface which moves at a preselected, controlled, rate along a time axis, an electrothermal print head having an array of separately activated electrothermal printing elements engaging said thermosensitive recording surface along a recording axis generally perpendicular to said time axis and a controller which generates command signals to said printhead for selectively activating the electrothermal elements of said printhead, in accordance with an input responsive to the magnitude of a preselected parameter, such that the location of activated ones of said electrothermal elements, along the recording axis, corresponds to said input.
