The unit (10) has a horizontally oriented platform (14) for detachably connectable accommodation of a printing unit module (16). A web of a printing substrate e.g. label, is printed during a printing process e.g. offset printing process, in cooperation with an impression cylinder (12) by the module, where the web of the printing substrate is guided over the cylinder. A retaining element (20) is provided for exertion of magnetic force, so that a position of the module is fixed on the platform. The element includes a permanent magnet such as neodymium-iron-boron magnet or cobalt-samarium magnet. |
