title: IOS print pdf with minimal margins
body: <p>This must be quite simple but I can't seem to figure this out.</p>
  
  <p>I've managed to implement the code for printing an PDF from my App. Problem is, the PDF has quite some whitespace around it and with the default margins... it's just not how I would like the page to come out of the printer.</p>
  
  <p>So, I'm trying to reduce the margins to minimum. How would I go about this? Do I need to use a custom UIPrintFormatter, UIPrintPageRenderer or UIPrintPaper. In which method from UIPrintInteractionControllerDelegate would I need to change things?</p>
  
  <p>I know it can be done because when I print the PDF from Apple's iBook App, margines are significant less.</p>
  
  <p>Thanks.</p>
