I didnt say it was good looking 
just tidy solution for tablet terminals…My preference would always be drawer and printer under counter where cables etc dont matter so much anyway.
At a glance it looks a bit plasticy and imagine it isnt cheap.
No, its not opening.
but still i can open the drawer using their application called :Printer Utility mpop
right, i use it with tablet.
its has Bluetooth also yoy can connect the tablet and the pos with Bluetooth or using USB
Is mpop is an executable then you could create a script that runs that executable?
If there is only one USB i would expect this is for the printer and its wired a similar way to normal internally.
Did you try emres link?
