Abstract
In the method and apparatus for printing bar codes on cartons disclosed in the specification, cartons on which bar codes are to be printed are conveyed in succession in either direction past a heater which heats a selected portion of the carton surface and a hot melt ink jet printer which prints a bar code on the heater portion of the bar code surface. The carton surface portion is heated to a temperature which is above ambient temperature by an amount which is equal to about 40% to 100% of the difference between ambient temperature and the solidification temperature of the hot melt ink.
