This is not really an issue, sorry.

I'm trying to connect a printer using usb4java, the standard java print method doesn't allow a bi-directional communication and then I need to use a low level exchange between PC and printer.

I successfully tried to exchange data using windriver installed with ZADIG, but I'm wondering if is possibile to use the standard usbprint driver automatically installed in Windows.

This is the error when I try to use usbprint driver:
Exception in thread "main" javax.usb.UsbPlatformException: USB error 12: Can't open device Bus 002 Device 003: ID 0755:2026: Operation not supported or unimplemented on this platform

Do I have any other chance?

Thank you very much.
