I've wanted something like this for a long time to print recipes that I'm about to cook. I don't want my phone in the kitchen getting gunk on it, so I'll usually print on paper, get the gunk on the paper, and then throw it out.

I'm not going to create a recipe PDF and load it on an e-reader. That's too much work. But I will happily press control-P on a recipe web page and select the eink display as the target.
