摘要

Provided is a print medium for use in a printer. The print medium has a laminar substrate defining first and second opposite faces. The print medium further has coded data distributed as a two dimensional pattern across a print area of the print medium. The two dimensional pattern comprises pattern elements, each pattern element encoding the two dimensional position of that pattern element in the print area. The print medium further has an orientation indicator indicative of an orientation of the two dimensional pattern.
