Print Pdf from javascript embed tag

Question

I have a PDF file and I am trying to print it via Javascript. I have tried this embed trick: Silent print a embedded PDF however, the print function never becomes available

Answer 1

With Javascript, I am not sure we can do this. However can be achieved using script injection into the pdf file. If my understanding is correct this is what Google does.

For example.

1. Open the url : https://drive.google.com/viewerng/viewer?url=http://www.energy.umich.edu/sites/default/files/pdf-sample.pdf
2. Now click on print icon.
3. As you can see a new window with print command injected into the pdf is opened. Once the pdf is loaded the built in print command is triggered. You can see the print triggered whenever you refresh the page. That means the print behavior is attached to the document load event.

We can use iTextSharp to simulate above behavior.
