Why is the 'print' option missing when right-clicking a PDF?

Thanks to Arc on the Windows 10 Forums for finding the solution!

The right click print option will be available after installing a [PDF application] with print capability. Install Adobe Reader DC or Nitro PDF Reader. Associate the PDF with it. Select multiple PDF files in a folder. Right click on the selection.

Context menu with Adobe Reader DC as default PDF reader (print available):

Context menu with Microsoft Edge as default PDF reader (no print option):
