Interactions between JSLs, catalogs, and jobs

Before starting to develop the JSL for your application, consider the interactions, similarities, and differences between various JSLs, catalogs, and jobs. Remember: although a printing system can have only one JOB or JDE in effect at a time, you can still create JSLs with multiple JOBs or JDEs, and switch between the JDEs by using DJDEs in the data stream.

•What characteristics are used globally, if any, for all of the applications at your site? For example, do all jobs use the same host, format, paper size, page orientation, block or record length, test criteria, DJDEs, error responses, accounting requirements, fonts, or forms?

•What names will you call the JSL and catalogs or individual jobs within the JSL? Use names that will be meaningful to you and others who may use the application.

Paper sizes and page frames

The printing system considers paper sizes in terms of page frames, which are boundaries associated with a page as a unit of printing or imaging. The system defines three page frames:

•Physical page

•System page

•Logical page

In addition to paper size, you must consider edgemarking and non-imaged elements when you design the pages of your applications.

System page The “system page” is the maximum image area of the printer for the paper size. The system page size varies, depending on the size of the paper for your job.

Physical page The “physical page” is the size of the paper itself. You may select any page dimensions within an 8 by 10 inch / 203 by 254 mm minimum and a 14.33 by 17 inch / 364 by 432 mm maximum.

If your system is configured with the small paper kit option, your minimum page size is 7 by 10 inches or 178 by 254 mm.
