Abstract
Processes and apparatuses print documents containing embedded interactive code (EIC) information by the use of custom postscript commands that are printer independent, with little overhead when printing, smaller print file size, and faster print times. In order to determine the postscript commands, the EIC array may be represented as a bit for every point, as EIC symbols in which each kind of EIC symbol is a glyph of a font, or as graphics procedures. The postscript approach may be selected based on memory and printing time requirements.
