"Export sheet to PDF" generates blank PDFs

[Sonja_Bauernfeind]

Qlik Sense fails to export a sheet to PDF and returns a blank page. 

When exporting an object as an image, the error:

An error occurred during export. Please try again.

Environment:

Qlik Sense Enterprise on Windows 

Resolution:

1. Verify if port 4899 is available. Unblock if it is not. 
2. Check the System_Printing log to see if the following error message can be found:
   
   Failed to connect to an IPC Port: The system cannot find the file specified. Server stack trace: at System.Runtime.Remoting.Channels.Ipc.IpcPort.Connect(String portName, 
   
   If so, please continue the following:
   1. Go to  C:\Windows\Microsoft.NET\Framework64\v4.0.30319\config\
   2. Make a backup of machine.config file first
   3. Open machine.config to see if the following line is included:
      

      <commonBehaviors><endpointBehaviors><Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior/></endpointBehaviors><serviceBehaviors><Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior/></serviceBehaviors></commonBehaviors></system.serviceModel>​

   4. Delete this line and save the file
   5. Restart QlikSense printing service
