SYMPTOMS

ENVIRONMENT

• NuGenesis 9 LMS

CAUSE

The Postscript Simulation option is activated the for WatersLMS PDF Printer.

FIX or WORKAROUND

1. Disable PostScript simulation.  This is disabled by default starting in NuGenesis 9.3:
   1. On the LMS Server, open this file in Notepad with Admin rights: Drive:\inetpub\wwwroot\WATERSLMS\web.config
   2. Look for the following line:
      • <add key="PDFREPORTSIMPOSTSCRIPT" value="1">
   3. Change the value to 0
   4. Save and close the file

The impact of turning off the Postscript Simulation option for WatersLMS PDF Printer is only on the generation of PDF reports from the Document Editor screen: Document, Document History, and Document with Audit Trail. No additional changes affect NuGenesis LMS behavior.
