The newest P800 driver 10.01 will not communicate with between LR and the P800 . Works fine thru airplay but then I would be using a limited print driver ..no 2880 option for example .
We're sorry to hear about the driver not working with Lightroom, could you please let us know what exact version of Lightroom you're working on and which operating system are you using?
Also, could you try reverting back to a previous version of P800 driver and let us know if it helps?
