PDL principles and procedures

What does a JSL specify?

A JSL is a set (“library”) of commands that specify various aspects of a print job, including:

•What portion of the variable and fixed data to use

•Placement, font, and point size for the variable and fixed data

•Which fonts, forms, images, signatures, and logos to use

•What paper stocks to use for the job

•Page layout

•Banner page recognition and processing

•How many copies to print

•Messages to the operator

•Use of black or colored ink for text and images (see the second note below).

NOTE: You cannot create forms at the DP EPS controller, because it does not have a forms compiler. Forms specified in a JSL must be created as separate files at your host, a workstation, or the controller of another laser printing system. You can then import these forms onto the system disk from diskette or tape, or download them from your host system using the FILE DJDE or the File Transfer Protocol (FTP) process.

NOTE: You can create highlight color JSLs on a monochrome system using many of the color related PDL commands and parameters. The JSLs you create on the monochrome system can be used on the Xerox highlight color laser printing systems (4850 LPS, 4890 LPS, and DP92 LPS). If you use color JSLs to print jobs on monochrome systems, the jobs print in black and shades of gray. (The shades of gray that appear on the printed output depend on the inks that are specified in the JSL for the colored areas.)

JSL command levels

There are many PDL commands available for your job source libraries, many ways of organizing them, and virtually infinite combinations you can use to create applications with PDL. There are, however, a few programming rules that you must follow when creating a JSL. If the JSL is not structured according to these rules, the system may not recognize or obey the commands you enter.
