title: iOS - points, pixels and printing
body: <p>I am creating a UIImage that I want to print using iOS. The printing type will be</p>
  
  <pre><code>printInfo.outputType = UIPrintInfoOutputGeneral;
  </code></pre>
  
  <p>or in other words, using regular paper. </p>
  
  <p>As far as I read, iOS will print at 72dpi. So, if I want to print a UIImage with a 2x3 inche size on paper I need to create this image with 144 x 216 points, but how much is it in pixels for that UIImage? or in other words, which size should the image has?</p>
  
  <p>thanks</p>
