Abstract
A technique for efficiently using media-type identifier code on print media and for processing that code, once read, to select the appropriate print mode for a printer that is to print onto that media. The system of the present invention minimizes the number of bits of data that must be associated with (hence, marked on) a sheet of print media to convey adequately the information as to the type of media, and is inherently backwards compatible. The invention uses simplified encoding and algorithm processing, which, in a preferred embodiment, includes a look-up table for storing known media-type code with associated print modes. A distance algorithm is used for locating the most appropriate print mode for given media-type identifier code that is not found in the table.
