I am not using Windows driver. How should I connect the printer?

Connect the system as follows if you use POS system or Logistics system without using the Windows driver.
1. Check whether the printer is connected properly.
2. Install the POS System and run the system.
3. Move to the printer setting menu of the POS System.
4. Set the Port where the printer is connected.
* If the port is serial, check the Baud rate setting one more time.
