Identifying which printer definition is involved in VTAM applications

For print jobs that VTAM® applications (using NetSpool) sent, you can determine which printer definition is involved through the LU names identified in messages and other output.

The primary LU (PLU), which is the application's LU name, appears in messages and in the SYSOUT data set. The secondary LU (SLU), which is the printer's LU name, appears in messages and in the printer definition. Both the PLU and the SLU also appear in the VTAM definitions.

The printer name in the printer definition being used by NetSpool also can appear in error messages.

To check which Printer Inventory NetSpool is using, see the INV= parameter on the NetSpool startup procedure JCL for the instance of NetSpool involved in the problem.

You can use Infoprint Central to find jobs. On the Work with Print Jobs panel, enter the LU name in the Submitted to field. For more information, see the online help for Infoprint Central and z/OS Infoprint Server Operation and Administration.

You can use the DISPLAY command with LUNAME, SELECTED, or STARTED to see diagnostic information, including the printer name. This can help you diagnose problems with NetSpool LUs. For more information, see z/OS Infoprint Server Operation and Administration.

For more information about the NetSpool startup procedure, see z/OS Infoprint Server Customization.
