Opening the cash drawer on a Mac computer

    • Type "Terminal" and press [Enter].

  6. Click on the "Cash Drawer Control" tab
  7. We're there: Simply activate the "Open before Printing" option and save it with the "Set Default Options" button. You may need to confirm this with your computer password.
  8. Done! Now just print and test that the cash drawer really opens.
