Abstract
A controller for operating a print head is described, which controller is designed to shift the activation points in time of the print head for printing of different lines of a print image on a recording medium relative to the line signal points in time, said line signal points in time being dependent on the transport velocity of the recording medium, such that the print head is operated with quantized operating frequencies from a set of predefined quantized operating frequencies. The print quality of the print head may thus be increased.
