A device for printing on hollow bodies has a plurality of printing units each having a printing cylinder. At least one of the printing units has an inking unit having a chambered doctor blade that provides printing ink. The chambered doctor blade system has at least one ink pan and a doctor blade holder in a single assembly. The single assembly of the chambered doctor blade system is retained in the inking unit only on one side. The assembly of the chambered doctor blade system forms a cantilever arm on a side frame of the inking unit. The assembly of the chambered doctor blade system can be moved axially parallel to the anilox roller and can be removed from the inking unit by that movement.
