VIPP

Functionality

In native mode, an application program uses the following operators to control how data is placed on a page:

•

•

•

•

•

•

•

•

•

Orientation (P, L, I, J)

Font selection (scaling, color/gray level, and outline)

Absolute placement coordinates

Text alignment (left, right, and center)

Rotation to any angle

Linespacing

PostScript forms merge (several per page; may be produced by virtually any PostScript emitter)

Image merge (including TIFF header interpretation, scaling, rotation, and CCITT Group 3 and 4).

Decomposition Service forms merge.

In line mode, you must place a job description ticket (JDT) call at the start of the data to initiate VIPP in line mode. The JDT describes the layout of the printed job and includes the following operators:

•

•

•

•

•

•

•

•

•

•

Orientation

Margins

Characters per line (CPI) and lines per page (LPI)

Font selection (including automatic scaling to required CPI/LPI)

Font indexing

Automatic frame and zebra generation

Form merge

Page numbering

Cycle form (printing of data multiple times with different forms)

Cycle feed (printing of data multiple times on different paper).

Operating environment

VIPP is not a converter that takes source or other PDLs and translates them to PostScript. It is contained in the PostScript decomposer as a set of subroutines callable from within the PostScript language. VIPP is independent of the printer and level of PostScript being used, and supports the entire DocuPrint NPS family of products.

VIPP is supplied as a PostScript prologue that is loaded into the interpreter as part of startup. Each copy of the dictionary is licensed to a particular printer and functions only on that printer.

DocuPrint NPS supplies a demonstration license that allows printing of VIPP documents up to 200 pages in length, without a specific printer license. A license is required for longer documents.
