POS won't open the cash drawer
Cash drawers connect through the receipt printer, not directly to the computer. If the printer is offline or the cable is in the wrong port, POS can't trigger the drawer.
Most cash drawers don't connect directly to a computer. They connect to the receipt printer using an RJ11 cable like a phone line. If the printer is offline, the drawer won't open from POS no matter what.
