• The barcode format CODE39 is used by KoalaBrain for printing on invoices and receipts
  • This is a widely used format which has a high compatibility with ESCPOS receipt printers and outputs receipts of an appropriate width and density for general use
  • Your webcam which you'll be using to capture barcodes needs to be attached prior to starting the KoalaBrain application, or errors will be shown on screens which try to access the camera
  • If you are using a "Keyboard Emulating" infrared barcode scanner, it will need to be compatible with the CODE39 standard
