USB-B port on side of case

Hi, just purchased a 2nd hand M200, hardware V03 and best of all, only 242hrs print time.
Not new to Zortrax as i use a M200+ at work, and also have access to another M200 and M300 in another dept.
Have upgrade the firmware from 1.1.1 that it came with to the latest for this printer, 1.3.1 (12 Feb 2019).

Question, what is the USB-B (square style) on the right hand side panel for?



The port you are referring to has no actual purpose.

At the time we were testing some possibilities for transfer, but finally it was decided that SD Cards were the safest and the best solution.

Best Regards
