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.

The printing device according to claim 10, wherein i=k and i and k are integers greater than zero. 14. A franking machine, comprising: a printing device, including: a print head operating according to an inkjet principle; and a control device actuating said print head for producing a two-dimensional barcode, the barcode containing a matrix composed of a plurality of image fields, the image fields containing at least one first image field being printed with a plurality of image points by said print head and at least one second image field being substantially unprinted, said control device converting barcode data defining a position and size of the image fields into actuating signals for said print head, said control device configured for converting the barcode data into the actuating signals for said print head such that the at least one first image field being printed with a lower number of the image points than corresponds to the barcode data. 15. A two-dimensional barcode, comprising: a matrix composed of a plurality of image fields, said image fields containing at least one first image field printed with a plurality of image points by a print head operating according to an inkjet principle, and at least one second image field being substantially unprinted, said at least one first image field being printed with a reduced number of said image points such that a printed area results in said first image field, said printed area being substantially at most equal to an area of said second image field, said image points being omitted in at least one first edge section of said first image field. 16. The two-dimensional barcode according to claim 15, wherein said printed area of said first image field is smaller than said area of said second image field. 17. The two-dimensional barcode according to claim 15, wherein the barcode is produced using barcode data defining a position and a constant size of said image fields, and said first image field is printed with a smaller number of said image points than corresponds to the barcode data. 18. The two-dimensional barcode according to claim 17, wherein said at least one first image field has a smaller size than corresponds to the barcode data. 19. The two-dimensional barcode according to claim 18, wherein said first image field is disposed in a region of the barcode which contains no useful information. 20. The two-dimensional barcode according to claim 15, wherein at least one first row of adjacent said image points is omitted in said at least one first edge section of said first image field. 21.
