Abstract:
A process of controlling printing of a digital image to be printed onto a substrate in a printer comprising creating the digital image on a drive computer for the printer, transmitting the digital image to an encoding device coupled to the printer, encoding the digital image onto a removable memory carrying device having an integrated circuit memory for receiving and holding the digital image, encoding an algorithm into the memory of the printer, using the algorithm for generating a number as a function of an input of a discrete number, the number generated by the algorithm providing a secondary password for comparison with inputs to the printer memory, and providing the same algorithm as in the printer memory at an off-site location, counting a discrete dynamically changing parameter in a counter in the printer as printing operations proceed to provide a counter output, using the counter output for an input to the algorithm in the printer memory and for an input to the same algorithm off-site to provide matching numbers based upon dynamically changing conditions of the printer.
