What is VIPP? Xerox Variable Data Intelligent PostScript Printware (VIPP) is a powerful system of fully compliant PostScript technologies for the production of personalized documents. The FreeFlow VI Interpreter refers to the software used to interpret the VIPP commands. VIPP is used to discuss anything related to the VIPP commands or VIPP based applications. VIPP consists of a set of macros that reside on the PostScript interpreter, eliminating many of the time-consuming steps associated with traditional variable information workflows by enabling Dynamic Document Construction (DDC) at the printer.
