I activate the Soft Proof tool (View | Soft Proof | Custom). I will be printing to Epson's Enhanced Matte paper, so I choose a custom ICC profile I've created for that paper on my printer (top right). I click OK to leave the soft proof active.
The soft proof shows me that the deep shadows on the cliff below the castle are going to lose detail (here). So I'll bring them back into the printable range with a Levels Adjustment layer. I increase the shadow value of the Output levels (below) until the abrupt transition disappears from the face of the cliff.
