Abstract: A manual, or hand-held labelling device has a printing apparatus and a pivoting lever on which pivoting lever there is a journal pivot pin on which an inking roller can be loosely mounted. For axially securing the inking roller on the journal pivot pin, within the housing of the manual labelling device, there can be at least one raised, guide track in the form of a circular arc, on the housing of the labelling device, and on the side opposite to the pivoting lever. This guide track essentially corresponds to the path of the inking roller on the pivoting lever as the pivoting lever is moved during a labelling operation, and thus supports the inking roller from moving axially off of the pivot pin during movement of the pivoting lever during the labelling operation.

Abstract: A method of bar code printing is disclosed. The bar code is printed directly onto packaging material associated with the product, and in that the ink used to produce the bar code is such that indicia constituting the bar code can be discriminated regardless of the background onto which the bar code is printed.
