title: ESC/POS "Select bit-image mode" vs "Print raster bit image"
body: <p>I'm working on some code to print an image from an Android device to a Bixolon SPP-R200. From what I can tell, it emulates ESC POS. I noticed that there are two commands for printing images. "Select bit-image mode" (<code>ESC *</code>) or "Print raster bit image" (<code>GS v 0</code>).</p>
  
  <p>What's the difference between these two commands? Why would I choose one command over the other?</p>
