Operating System -
Your printer does not have an Operating System, at least not one you would recognize.
The Operating System / version used with the printer comes from the computer or device you are using to connect to the printer.
For example, if you have a Windows machine and you are running Windows 10, software and applications you run when using the printer must be compatible with Windows 10.
