Won't boot after upgrade unless I delete hp_io_enabler_compound.kext

After upgrading to El Capitan I cannot boot my Mac only unless I delete in safe boot the following extension:

hp_io_enabler_compound.kext

the funny thing is that it is created after each login. I think by using my HP printer. So two questions, is there a way to fix this and be able to start even when this .kext exists or is there a way to prevent the .kext from being created each time? Will the printer work ok after that?

Any ideas?

Mac Pro (Early 2009), OS X El Capitan (10.11)

Hum..

at a further restart

I wouldn't be surprised to find some HP utility loading at launch. Look in LaunchAgents and LaunchDaemons folders.
