System and method for printing packages

A system for printing comprising:

• a conveying system that transports an object toward a print system;
• a control system having a first queue and a second queue, wherein the first queue has a plurality of blocks of print commands stored therein in an ordered sequence;
• a sensor that reads a first identifier encoded in indicia on the object;
• an image generator that selects an oldest block of print commands from the stored plurality of blocks, wherein the oldest block of commands is associated with a second identifier;
• and
• a print controller;
• wherein the image generator determines whether the first identifier is associated with a second identifier and, if so, causes the print controller to print content specified by the selected block of print commands on the object, otherwise stores the oldest block in the second queue.
