title: ZPL file to image
body: <p>I have UPS generated label with ZPL which I want to print. I can do it via printer driver but it is not convinient.</p>
  
  <p>I could generate GIF file but after resizing to 4x8 inches it looses quality.</p>
  
  <p>Is there a way to convert ZPL file into common graphic format so I can just open and print from a file ? Preferably in PHP.</p>
