I don't understand why is your post relevant to the topic at hand? I assume you're not quite a target market for printers then? Or is it a question because you can't imagine anyone still using paper in the world?
I like printing papers and some other material. I know there's e-ink, but they are just worse than pen and paper. I also like printing train tickets so I don't need to stress out about my phone battery. Occasionally I have to mail the government something too.
I never used paper for anything else, so from my point of view, it's not on the decline. But just steady and stable.
I prefer reading papers on paper, with fountain pen to make notes. It is easier for me to focus on compared to electronics devices (well, I am answering on HN instead of doing things I should be doing)...
