What would be the use case of this? I have a remarkable 2 and there's the official Read on Remarkable extension that automatically sends a pdf of the page you're on or the book or whatever to your Remarkable. I'm not sure if it works on Remarkable 1 but there isn't any documentation on it being unsupported.
