| 1. A printer for printing, onto a surface, an interface of visible data and machine-readable coded data, the visible data
being based at least partially on document data which includes identity data indicative of at least one identity associated
with a region of the interface, the printer comprising:
a printhead;
a processor for generating dot data for the printhead using the document data, said processor including a coded data generator
configured to generate the coded data based at least partially on the identity data;
at least one visible ink channel dedicated for printing the visible data; and
an infrared ink channel exclusively dedicated for printing the coded data,
wherein the printhead is configured to print the interface onto the surface by printing the visible data and the coded data
substantially simultaneously.
