Hi, I'm trying to set up this POS system. I'm new to this thing, so bare with me please. I have 2 POS systems side by side. I will refer to them as POS1 and POS2. Both of the POS is attached to a printer and it works fine. My real problem is that I can ring up orders on both machines, but I can't close out day on POS2. POS1 seems to be working fine and I can close day with it. I recently had POS2 crash on me with the blue screen of death. I had to re-do everything. Does anyone know what I need to do?
