The invention provides for optional printing at a pont of sale (POS). The invention provides a system and computer implemented method for printing information at a POS relating to a purchase transaction at the POS, comprising printing a second alternative instead of a default print, or printing both a default and a second print, in both cases dependent upon the second print being timely delivered to the POS printer. Preferably, the second print depends upon processing business rules related to color in the print. |
