A combined printing and binding device which is designed to print and bind
a multi-page interactive publication. The device includes a communicator
which is designed to receive a set of page descriptions from a computer
system. The page descriptions correspond to the pages of the interactive
publication and each page description includes content information and
coded data. The device also includes a printer which is designed to
print, onto media sheets, each of the page descriptions received by the
communicator. The printer does this by simultaneosly printing the content
information in visible ink and the coded data in substantially invisible
ink. The device also includes a binder that is designed to bind the
printed media sheets together to form the printed, bound, interactive
publication.
