It's often desirable to print articles or blog posts to PDF for easier reading. In fact you're almost always better off reading a cleaned-up printout than a noisy HTML page on a backlit screen.
Offline reading has fewer distractions; you can mark up the article with your own notes; and it's easier on the eyes. Active reading, underlinding and annotating improves comprehension and retention. If you read on the reMarkable tablet, as I do, then you don't to print to actual paper and save trees.
If an article is worth reading, it's worth printing and reading with a pen in your hand.
