Environment

• Qlik Sense Enterprise on Windows, version April 2020.

Resolution

Extend Qlik Sense Printing service timeout to allow for renderer service to finalize image export. 

1. Edit C:\Program Files\Qlik\Sense\Printing\printing.exe.config
2. Add or uncomment webrenderer-grpc-call-timeout-secs setting in file
3. The value to 30
   

   <!-- 
   =====================================
       Sense rendering configuration
   =====================================
   -->​
   <add key="webrenderer-grpc-call-timeout-secs" value="30" />

4. Save and close the file. 
5. Restart Qlik Sense services.
6. Repeat on each node that has a running Qlik Sense Printing service. 

Cause 

Qlik Sense Printing service internal communication over gRPC reaches timeout before an exported image is finalized. The default timeout is 10 seconds, which may not be long enough on a less powerful server or when the server workload is very high.
