ABSTRACT:
A method and an apparatus for printing at desired positions on four sides of a box shaped object of an arbitrary size, automatically, quickly, without complicating a configuration of the apparatus excessively. In the apparatus, carrier rollers are rotated in a normal direction in order to place the box shaped object at a predetermined printing position on the carrier passage; one corner of the box shaped object at a predetermined printing position on the carrier passage is held by a holding mechanism; desired printing patterns are printed on one side of the box shaped object facing toward the printer by printer; the carrier rollers are forcefully stopped while the printer prints on one side of the box shaped object facing toward the printer; the carrier rollers are rotated in a reverse direction such that the box shaped object is rotated by 90.degree., by obliquely arranged members of the carrier rollers which are arranged along the printer in an orientation oblique to the carrier passage, around the corner of the box shaped object held by the holding mechanism; and the holding mechanism is released from said one corner of the box shaped object after the box shaped object is rotated by 90.degree..
