Abstract
An inkjet printer having at least one print head in which at least one edge region nozzle at the edge of the print head is not activated for the printing of a print image, but nevertheless is activated at least temporarily with non-ejection pulses without ink ejection. Intensity fluctuations of the dots of a print image that are printed by the remaining nozzles of the print head may be reduced via the activation of an edge region nozzle with non-ejection pulses.
