I have set up Sambapos 4.148 on my laptop and each menu item has an associated barcode corresponding to the items on the printed menu. When the barcode is entered from the numberpad, the associated item is correctly selected when I press enter, which is what I want to happen.
My problem is that I want to use this feature with a touch screen and no keyboard, hence no enter button so how can I simulate pressing the enter key to allow selection of the items?
