title: Change the date format at the header - NGX-Print
body: <p>I'm using at my application the ngx-print with angular 8.
  when I click print-button, it added at the header a date,  with format mm/dd/yy. 
  I want to change that to dd/mm/yy.</p>
  
  <p>Unfortunately, I didn't find any documentation for it. </p>
