Abstract
A computer-implemented method is designed for printing on regular digital printers of a coding pattern consisting of regularly spaced code symbols. In the method, a page-describing code (e.g. in PostScript programming language) is generated for the printer. The generation of the page-describing code is based a character definition set which assigns a set of characters to represent a set of mutually unique groups of the code symbols. By mapping the set of mutually unique groups against the coding pattern, the location of corresponding groups within the coding pattern can be identified. Each of the corresponding groups is then represented by its assigned character in the page-describing code. The resulting page-describing code is small in size and has a reduced set of printer instructions that can be processed efficiently by the receiving printer.
