Hello Banibrata,

Thank you for pursuing the line of investigation I suggested. However,
you appear to have resolved your issue:

My initial thoughts did turn to IPP-over-USB but I put them to one side
because my understanding was that using a vendor driver to print was
not possible at all, whereas you were able to print even though printing
was degraded.

It would be good to confirm that this device is capable of working with
the IPP-over-USB protocol. Please give what you get for

  lsusb -v | grep -A 3 bInterfaceClass.*7

Cheers,

Brian.
