Print receipt with Google Cloud Print

Google cloud print (GCP) is a printing technique embraced by RockPOS to solve problem of printing receipt with special symbols (eg: other currencies than US Dollar and other language accents) as well as to allow printing receipt from tablets or phones. So:

  • Use QZ tray if:
    • Your system is in English
    • Currency is US Dollar
  • Use GCP if you’re in 1 of these cases:
    • Your system is NOT in English
    • Currency is NOT US Dollar
    • You want to print receipt from tablets or phones
    • If you have any issues using QZ tray
