- When any POS software ( sell software) is sending print order to POS machine (Thermal printer), so database to print by Printer Logger save and analyze by normal text and send it to API that it was a configuration ready.

- Having a monitor ( form) to a configuration that has port and baud rate

- Having a monitor (form) to a configuration that has an API server to send the database.

- Running from windows 7 and over. Both versions are 32bit and 64bit ( or can build how to 2 apps for 2 versions)
