  Hi Mohit,

  Just to let you know there is an issue using the print option in the jsViewer in Chrome 77, when embedding it in an iFrame, when clicking print you just get an empty page, and the following error:

  Failed to load 'about:blank' as a plugin, because the frame into which the plugin is loading is sandboxed.
  

  Works fine in IE and Edge.

  I am currently looking into what can be done to resolve this.

  Hello Kevin,

  Sorry to mention that I am not able to reproduce the issue at my end. What I did:
  
  1: Create a JsViewer application
  
  2: Use the above application in IFrame like as follow:

  3: Open in Chrome 77 and click on print button

  Request to please confirm if I am missing something at my end.

  Thanks,
  
  Mohit

  Hi Mohit,

  We use a cross-origin iFrame, of which is secured by sandbox.

  I have had to sandbox it due to the Invariant Violation in chrime 77.

  For your reference, in case this is raised another time.
  
  I Fixed this issue by adding, the following security attribute to the sandbox

  allow-popups-to-escape-sandbox
  

  Thanks

  Kev
