Secure Print on Canon ImageRUNNER MFP

Hi!
I'm trying to setup a brand new Canon ImageRUNNER C5255 Multi-Function Printer.

Canon recommend to use their own printerdriver: UFR II-driver (This is not PS/PCL).
We are goint to use Secure Print.

I createt a new iPrint Agent and uploaded the driver to the Broker (NW6.5-SP8)

Problem is that Secure Print doesn't work. The printjob is sent to the machine, but the job is canceled.
If i disable Secure Print, the it works.

So my question is:
- Is it possible to get Secure Print to work in iPrint?
