Determining where to print JES output

Each NPF FSS writer is associated with 1 or more logical printers (which was assigned an output class or classes during JES initialization, or in some cases, by JES console commands). When an NPF FSS writer and associated logical printer are active, the NPF FSS writer processes all JES output that matches the output classes assigned to the logical printers. When the Network Print Facility receives the output, it uses the output class, destination, and forms associated with the output to determine LPR options and which LPD printer queue should receive the output. This determination is made though the routing file described in the following chapter.

For example:

Output 1 has JCL parameter CLASS=C, FORMS=1000, DEST=LOCAL
Output 2 has JCL parameter CLASS=C, FORMS=1000, DEST=LOCAL
Output 3 has JCL parameter CLASS=C, FORMS=1000, DEST=DEST1
Output 4 has JCL parameter CLASS=C, FORMS=2000, DEST=LOCAL

Output 1 and 2 will be sent to the same LPD print queue, which were defined to handle the combination of the class, forms, and destination. Output 1, 3, and 4 might each be sent to separate printers or might have a different NPF processing performed because they each have a unique combination of class, forms, and destination. For more information on printer destination mapping, see The routing file.

Note: The Network Print Facility uses the 1–8 alphanumeric destination name you specify through the ROUTING function of the EZAPPFL macro (MAJKEY parameter) to route output.
