In a method of printing a filled bag or sack (10) being carried on a continuously moving conveyor (11), a print head (19) is positioned in the path of the bag or sack and allowed to pivot about a predetermined axis in response to engagement with the bag or sack. The orientation of the print head (19) is therefore dependent on the particular portion of the bag or sack (10) passing beneath the head at any instant, and a printing fluid is discharged through at least one nozzle in the print head as the bag or sack passes beneath the head. |
