CEF rendering errors in NPrinting. Troubleshooting step: use benchmarks to test the importing image process
The benchmark application replicates the steps NPrinting follows to import images from Qlik Sense. It can be used to import many copies of the same image quickly and verify if there are any problems during the process. This must be used any time a report generation fails with "CEF rendering" error messages in the NPrinting Engine log files.
The benchmark creates specific log files in the NPrinting log folder and saves the imported images in C:\tmp.

CEF rendering errors became quite common and the logs are not detailed enough to understand the cause of the problem. The test described here gives useful information to troubleshoot the problem.
Here are the steps to configure the Benchmark:
Download the zip file from here and extract it in C:\Benchmark\ on the machine where NPrinting Engine is installed.
Open the Engine.Navigator.QlikSense.Benchmarks.exe.config file in C:\Benchmark\Engine.Navigator.QlikSense.Benchmarks with a text editor program.
It is necessary to re-configure the connection to Qlik Sense. Follow these steps:
