Abstract:
1. A print medium for use in a mobile device having a printer, the print medium comprising: a laminar substrate defining first and second opposite faces; first coded data in a linear-encoded data track extending in an intended direction of printing, the data track being disposed in a first data region on the laminar substrate, the first coded data encoding first information; second coded data distributed as a two dimensional pattern across a print area of the print medium, the two dimensional pattern comprising pattern elements, each pattern element encoding the two dimensional position of that pattern element in the print area; and at least one orientation indicator indicative of an orientation of the two dimensional pattern; wherein, the data track includes a clock track containing a clock code for providing a clock signal during printing onto the print medium, allowing registration between what is printed in the print area of the print medium and the second coded data.
