/usr/lib/cups/backend/ipp failed

Greetings

I can't print anything.  When I try to print I get
"/usr/lib/cups/backend/ipp failed" regardless of printing test page or
anything else. The printer is Lexmark C750, With a proper PPD from
Lexmark. I used the WEB interface for setup. There is only one printer
defined. It's set as default printer. The CUPS setup looks ok (see
below). I've done some googling without finding anything conclusive.

I can ping the printer.
I've previously successfully used URI ipp://192.168.1.248/ipp/.
I've set LogLevel to "debug". I got a _huge_ file. Couldn't see anything
special. Not included. Loglevel is currently set to "info".

Can anyone point me in the right direction to solve this?

Regards,
Durque
