Solved! Standard usb printer cable to xlr???

Solution
"Standard printer USB cable" is usually USB-A (computer end) to USB Type B (squarich end). It is all digital interface.

XLR is audio cable, and it is analogue. So, in order to use that USB cable, you need an external USB sound adapter with XLR interface, or just XLR-to-USB converter cable like this one
