I’m able to scan a barcode and the number will be inserted into a text field. But what I need is the Grabba unit to scan the barcode, insert into the text field and submit the form all by just pressing the trigger. Basically, I need to simulate an enter key press after the carriage return.

1. In the bottom of the Grabba Browser app there are five action buttons, click the one in the right to access to settings.
2. Scroll down up to a section called: Keyboard Wedge.
3. Click over advanced
4. Activate the option Simulate Submit
