After printing a receipt, you can only pop the cash drawer twice more doing no sales, no more after that unless you restart the POS, not the computer.
We?ve tried another cash drawer, printer, serial port(and settings), and combinations thereof with no difference. We?ve used this same hardware setup before with no problems. Exception: The system is set up to log in to the register for every sale.
Is this a problem with setup, the software, or the hardware?
