title: Run silent print via Chrome App in Kiosk mode
body: <p>Does anyone know a way to silent print via a Chrome App?</p>
  
  <p>I'm developing a chrome app for a KIOSK system which runs Chromium OS. I need to print a receipt via a Chrome App, which I already did. The problem is that print dialog box appears once print process is started.</p>
  
  <p>Is there any way around this? </p>
