A method of generating a second mail item in response to a first mail item, the first mail item comprising a printed interface surface having visible information and coded data printed thereon, the coded data being indicative of the identity of the first mail item and of a plurality of map locations on the surface, the method including the steps of:

receiving, in the computer system, indicating data from an optically imaging pen, the indicating data including data regarding the identity of the first mail item and data regarding a position of a nib of the pen relative to the printed surface, the pen generating the indicating data using at least some of the printed coded data optically sensed by the pen; and

generating the second mail item using the indicating data from the pen.
