A printer is activated to print a barcode on a lower face of the uppermost printing paper. The front edge of the uppermost printing paper is moved to pass through the cutter and the paper output roller unit. The paper delivering motor is then stopped, and a rear edge of the uppermost printing paper is cut under operation of a paper output motor.

Abstract: Various trash can assembly embodiments are disclosed. In some embodiments, the trash can assembly includes a body and a lid assembly. The lid assembly can include a lid, and a multicomponent trim ring. The lid assembly can be rotatably connected with the body via a hinge unit. In certain embodiments, a flange of the trim ring is guided into and/or received into the hinge unit. A translating pin of the hinge unit can engage into the flange, thereby providing a rotatable connection between the trim ring and the body. In various embodiments, the translating pin is coupled with a handle to facilitate movement of the pin by a user during engagement of the trim ring and the hinge unit. A positioner can help to position the trash can against or adjacent to a wall or other structure. The movement of both the trim ring and the lid can be dampened.
