Hi I'm sorry if this has been answered before but I've looked and can't find the answer. I'm at my wits end at work with this and our "tech" guys can't seem to fix it so thought I'd ask here. So the only issue is with the till it won't open, when prompted or when sales are put through. When ever you do something on pos that would normally make the till open u get a icon please close till well the till is closed with this icon there you can't do anything you have to go into task manager and close pos and re open. Now all the cables are in and icon stays there even when we unplug till. Our set up is 1 till cable goes into back of computer receipt printer has 2 cables 1 into computer and one into router all are hp. Pls help if u can thanks
