This chapter describes how to create, insert, or reference these VIPP or 

PostScript command elements in the print data stream.
•

VIPP command — A VIPP command describes how the printer 

should process the data stream. VIPP commands control the page 

composition of a job.

•

VIPP Native Mode Prefix (NMP) record — An NMP record is a VIPP 

command that is preceded by the prefix %%XGF. NMP records are 

used within the data stream to dynamically invoke VIPP resources or 

features. 

•

Job Descriptor Ticket (JDT) — A JDT is a printer control file that 

contains one or more VIPP commands. The JDT must reside on the 

printer controller. In addition, the spool file must identify the name of 

the JDT to be used by the printer to process the data stream.

•

PostScript Data Structuring Conventions (DSC) packet — A 

PostScript DSC packet is an object that contains DSC statements. A 

DSC statement is preceded by the prefix %% and followed 

immediately by a DSC command (with no space between the prefix 

and the command). DSC statements are instructions that you want 

the PostScript document manager to apply to the entire job.

Refer to the Xerox Variable Data Intelligent PostScript PrintWare (VIPP) 

Reference Manual for detailed information about VIPP commands, NMP 

records, and JDTs. Refer to the PostScript Language Reference Manual 

for information about DSC statements.
Before you use VIPP command generation for the first time, make sure 

that you have:
•

Completed the installation process described in 

. This process includes 

downloading the separator page JDT called XDPSPR.JDT to the 

printer controller.

•

Addressed all network and, if applicable, duplex printing setup 

requirements for VIPP mode printers as described in 

,” of this manual.
