c550 biz hub and Mavericks OS x

I had the same problem with the apps crashing as soon as I tried to print.

I downloaded the newest driver from Konica Minolta (Canada) Version 4.8.0, Recreated the printer in the System Preferences.

After that, driver worked fine and I have been able to print.

My problem is: Print Job leaves the Mac, the Printer blinks shortly, nothing else happens after that.
Mavericks Driver is scheduled for May '14, but the 4.8 release notes state that it should work anyway.
