Xerox DocuPrint 180 manual Job source library JSL files

BASIC CONCEPTS

Job source library (JSL) files

Print description language (PDL) commands are used to describe the data layout and provide instructions for data placement on a page with or without an FDL-created form. The JSL file contains PDL statements defining the format of the input, processing requirements, and the format of printed output. When the JSL file is compiled, it is referred to as a job descriptor library (JDL) file and is referenced for printing a job.

Within a JDL file, there may be one or more unique definitions for different processing features, output formats, and tape formats. Each set of unique definitions represents a job and is called a JDE or a job.

A JDL (compiled JSL) file containing printing instructions for the DocuPrint 180 LPS is required to print any job on any configuration. Many specialized functions can be accomplished with PDL statement commands. Refer to the Xerox DocuPrint 180 LPS PDL Reference for specifics

Several basic JSL files are provided with the OSS; for example, ONLINE.JSL is provided for printing online jobs, a XEROX.JSL is provided for printing magnetic tape jobs, and so on. To meet specific application needs, any OSS-supplied JSL can be copied and modified. All Xerox LPS’s have as a standard feature the LPS Editor utility for the creation and modification of program source files (FSL and JSL extension files).
