Abstract: A laser printing system comprising a conveyor for conveying a group of containers, a container group packaging device for packaging a group of containers by a base material at the conveyor, if a conveyance speed when the group of containers packaged by the base material reaches a first region is smaller than a conveyance speed a predetermined time before the packaged group of containers packaged by the base material reaches the first region, the conveyor conveying the packaged group of containers by the conveyance speed when reaching the first region, and a laser printing device for laser printing the base material of the packaged group of containers when the packaged group of containers reaches a second region positioned downstream from the first region at the conveyor. Due to this, the identical base material is prevented from being printed on a plurality of times. Further, this may also include an end signal emitter for emitting a printing end signal after the base material is printed on.

Abstract: A laser printing system (10) comprising a conveyor (11) for conveying a group of containers (60), a container group packaging device (25) for packaging a group of containers by a base material (21) at the conveyor, if a conveyance speed when the group of containers packaged by the base material reaches a first region is smaller than a conveyance speed a predetermined time before that conveyance speed, the conveyor conveying the packaged group of containers by the conveyance speed when reaching the first region, and a laser printing device (50) for laser printing the base material of the packaged group of containers when the packaged group of containers reaches a second region positioned downstream from the first region at the conveyor. Due to this, the identical base material is prevented from being printed on a plurality of times. Further, this may also include an end signal emitter for emitting a printing end signal after the base material is printed on.
