Abstract

A printing device has a print head which operates according to the inkjet principle and a control device which actuates the print head for producing a two-dimensional barcode. The barcode contains a matrix composed of a plurality of image fields. The barcode contains at least one first image field which is printed with a plurality of image points by the print head and at least one second image field which is substantially unprinted. The control device is configured for converting barcode data which define the position and size of the image fields into actuating signals for the print head. The control device is configured for converting the barcode data into actuating signals for the print head in such a way that at least one first image field is printed with a lower number of image points than corresponds to the barcode data.
