Well, from the error message
"[Job 25] Unable to cancel print job."
I see that the printer is configured to use the IPP protocol. Could you try
to reconfigure the printer to use a different protocol, e.g. socket?
As the printer has a web interface for setup and maintenance, you should log
in there as an administrator and revise the protocol settings.
