Printing PDF using pdf.js

Question

I am embedding a single page PDF in a page using pdf.js and I want to be able to print just the PDF, not the whole HTML page.

Is this possible?

Answer 1

I had previously loaded a pdf document onto a canvas using pdf.js.

The canvas only contains one page. So This is what worked for me for a single page:

  var canvas = document.getElementById('pdfPage');
  var win = window.open('', '', '');
  var html = "";
  win.document.write(html);
  win.document.close();
  win.focus();
  win.print();
  win.close();

I still need to find out what is needed for multiple pages. If I do, I'll edit this answer.

I have to say this approach is not optimal, because it doesn't print the pdf page "camera ready" or in other words in it's original form. It prints an image of the pdf page. The difference is the margins that should not be there and the header / footer that should not be there, as they are not in the original document. Therefore, I'm going to be looking for an approach that prints it like the pdf.js viewer prints it -- in it's original form with fidelity to the orignal document.
