Abstract

A controller for a print head of an inkjet printing device is described that is configured to generate a virtual timing signal during a printing pause of the printing device, and to use the virtual timing signal for the generation of pre-ejection pulses in order to produce a reliable regeneration of the nozzles of the print head during the printing pause.
