OVERVIEW
Printing data
The 4050/4090/4450/4650 LPS can print the types of data shown
in table 1-5.
Table 1-5. Data types
Data type Description
Variable data Variable data changes from page to page. The LPS can merge
variable data with a form.
Fixed data Fixed data (FRM file) remains constant from page to page (for
example, letterheads and column headings). Forms data usually
refers to information found on preprinted forms or overlays.
Note: Generating forms at a host requires a host-resident forms
design software package such as Host Forms Description
Language (HFDL).
Any form suitable for computer printout can be described and
entered into system storage. Once stored on the system, a
form can be activated by referencing the name of the form in
the Job Source Library (JSL) file or Job Descriptor Entry (JDE).
All Xerox laser printing systems have a line editor utility for the
creation and modification of program source files (.FSL and .JSL
extension files).
Refer to the Xerox 4050/4090/4450/4650 LPS Command
Reference for more information on the LPS Editor.
Graphic data
(usually merged
with variable data
or fixed data) Graphic data (.IMG file) refers to digitized images (both line art
and continuous tone images) that are merged with variable or
forms data. Sources of graphic data include the following:
•
Graphic data generated by EPIC host-resident software
•
Scanned images from the Xerox 7650 Pro Imager (using
XPIW)
•
Scanned images from the 150 GIS.
Note: The GHO/GVG option is required on the LPS to process
graphic data.
Production process overview
The process of producing a job on an LPS can be broken down
into three distinct phases: input, special processing, and output.
Figure 1-1 shows this process.
