Environment:
- Qlik NPrinting June 2018
- Qlik NPrinting April 2019
- Qlik NPrinting September 2019
Cause
This error may have occurred because of some orphan processes named reporting_web_renderer. This may have resulted from an unexpected engine crash.
Resolution
Workaround:
A possible resolution could be to kill the engine process and then kill any subprocess called reporting_web_renderer in task manager. Alternatively, restart the server where the NPrinting Engine service is installed.
