title: Delphi: How to print a PDF without showing it?
body: <p>I have been looking online for some time now, but I still haven't figured out how to print a PDF file in Delphi without showing the document itself, or a print dialog. I just want to open a file without showing it, and print it to the default printer. </p>
  
  <p>I'm trying to print a batch of PDF documents, and there is no need for user interference. </p>
