Abstract

In a method or apparatus for controlling a printing process in an inkjet printing apparatus that has multiple print heads, a line scan is generated to print a print line on a recording material. The individual print heads are individually controlled with an offset relative to the line scan to eject printing ink, print data prepared for the printing being stored in a memory device upstream of the print heads. Print data units to be printed by the print heads are transferred from the memory device to the respective print heads in a same order with which they are printed. The order with which the print data units are transferred is controlled by request commands entered into a FIFO memory, each request command identifying a print head in the order of the transfer of the print data units corresponds to an order of the request commands in the FIFO memory.
