Abstract

In a method and a device to sort pixel data in a print data stream, a data sorting memory is used configured so that it can be written per column and read per row. The pixel data are entered per column into the data sorting memory in the order of the incoming print data stream. Via the per-row readout the pixel data are re-sorted into an order suitable to control the print head. The sorting can thereby take place in only one write process and one read process.
