Abstract
Data identifying a print head of a postage meter is registered on the print head by allocating a number of printing elements of the print head to represent a code identifying the print head. The allocated printing elements are not used for printing postage indicia. The print head may be an ink jet print head having resistive elements energisable to eject ink droplets from nozzles. In order to represent the code, the resistance of selected ones of the resistive elements allocated to represent the code is altered for example by fusing the resistive elements.
